title Algorithms of the Mind. The generative art of drawing
source International Conference on Generative Art
summary Throughout the disciplines of art and design, interest in the possibilities of algorithmic methods for generating two- and three-dimensional visual forms grows apace. Evidence supporting this observation may be found in the increasingly diverse range of contributions to the Generative Art conferences. Two research scenarios may be identified: 1 in which the generative process itself is the object of research, 2 in which the forms generated are the objects of research. The question of what criteria may be appropriate to the evaluation of such research is addressed in this paper. Lincoln and Guba's term "criteria of authenticity" is elaborated in a case study based on the author's research into teaching drawing to fine art undergraduates. Although the drawings produced are not computer-generated, it is argued that the concept of 'algorithm' as a set of rules for the generating of visual representations may be usefully applied to the mental ontological constructions, or 'mind-set', of the student. Such mind-sets affect the ways that drawings are constructed. It is suggested that a teaching method which enables students to recognise their mental algorithms as cultural constructions, may also empower them to reconstruct those algorithms in order to generate visual representations previously unimagined.

summary Architects are visual learners. The Internet has enabled interactive learning tools that can be used to assist in visual thinking of structural concepts, especially at the introductory levels. Here, we propose a visual approach for understanding structures through a series of interactive learning modules, or ’gizmos’. These gizmos, are the tools that the student may use to examine one structural concept at a time. Being interactive, they offer many more possibilities beyond what one static problem can show. The approach aims to enhance students’ visual intuition, and hence understanding of structural concepts and the parameters affecting design. This paper will present selected structural gizmos, how they work, and how they can enhance structural education for architects.

title Integrated design in a service marketplace
source Computer-Aided Design, Vol. 32 (2) (2000) pp. 97-107
summary This paper presents a service marketplace vision for enterprise-wide integrated design modeling. In this environment, expert participants and product developmentorganizations are empowered to publish their geometric design, CAE, manufacturing, or marketing capabilities as live services that are operable over the Internet. Theseservices are made available through a service marketplace. Product developers, small or large, can subscribe to and flexibly inter-relate these services to embody adistributed product development organization, while simultaneously creating system models that allow the prediction and analysis of integrated product performance. It ishypothesized that product development services will become commodities, much like many component-level products are today. It will be possible to rapidly interchangeequivalent design service providers so that the development of the product and the definition of the product development organization become part of the same process.Computer-aided design tools will evolve to facilitate the publishing of live design services. A research prototype system called DOME is used to illustrate the concept and apilot study with Ford Motor Company is used in a preliminary assessment of the vision.

summary Our architectonical environment is based on the material concept - entity whose control marks the relevance of the XX century: the atom. Across the threshold of the XXI century a new virtual entity - concept: the bit, spreads to became the basic unit of power - control - production, being its more dynamic evidence the phenomenon known as Internet, establishing complex relationships with groups constituted in the net like Virtual Communities, outlining metaphors that involve Urbanists and Architects inviting them as protagonist. Against this newest reality the Architect should change his vision of the typical CAAD work in relative isolation with his computer, until crossing the doors of the “digital reality”; we search to show the contemporary Architect as a manager coordinating multiple resources with different importance: into the alternative of building digital realities, inviting the architectonical students to integrated this Virtual Communities or conform his owns.

summary Virtual reality and cyberspace are extended spaces of the mind different from, yet related to, the spaces of fiction and ancient myth. These earlier spaces reveal how electronic media, too, may come to define our selves and our culture. Indeed, a better understanding of how we use space to think can lead to the design of better information environments. This paper will describe a range of traditional narrative spaces, revealing their varied relationships with the physical world. It will demonstrate the purposes of such spaces and how their function changes with their level of abstraction. A concluding review of current technologies will show how electronic environments carry on the traditions of these spaces in serving our cultural and psychological needs.

title The Intelligent Sketch: Developing a Conceptual Model for a Digital Design Assistant
doi https://doi.org/10.52842/conf.acadia.2000.137
source Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 137-145
summary The computer is a relatively new tool in the practice of Architecture. Since its introduction, there has been a desire amongst designers to use this new tool quite early in the design process. However, contrary to this desire, most Architects today use pen and paper in the very early stages of design to sketch. Architects solve problems by thinking visually. One of the most important tools that the Architect has at his disposal in the design process is the hand sketch. This iterative way of testing ideas and informing the design process with images fundamentally directs and aids the architect’s decision making. It has been said (Schön and Wiggins 1992) that sketching is about the reflective conversation designers have with images and ideas conveyed by the act of drawing. It is highly dependent on feedback. This “conversation” is an area worthy of investigation. Understanding this “conversation” is significant to understanding how we might apply the computer to enhance the designer’s ability to capture, manipulate and reflect on ideas during conceptual design. This paper discusses sketching and its relation to design thinking. It explores the conversations that designers engage in with the media they use. This is done through the explanation of a protocol analysis method. Protocol analysis used in the field of psychology, has been used extensively by Eastman et al (starting in the early 70s) as a method to elicit information about design thinking. In the pilot experiment described in this paper, two persons are used. One plays the role of the “hand” while the other is the “mind”- the two elements that are involved in the design “conversation”. This variation on classical protocol analysis sets out to discover how “intelligent” the hand should be to enhance design by reflection. The paper describes the procedures entailed in the pilot experiment and the resulting data. The paper then concludes by discussing future intentions for research and the far reaching possibilities for use of the computer in architectural studio teaching (as teaching aids) as well as a digital design assistant in conceptual design.

title Percept vs. Precept: Digital Media & the Creative Process
doi https://doi.org/10.52842/conf.ecaade.2000.261
source Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 261-264
summary The design of architecture, as well as all of the arts, is a creative act concerned with the expression of ideas through culturally significant and relevant form. In order for the creative act to transcend the authority or dictates of precedents or trends, it must be informed and guided by a process and not a product; one which reveals, but does not dictate, expressive, functional form. The initial impact of digital media on architectural design has been the ability to render the look of a final project or to create shapes that reflect the facility of the tool. Digital media also enables the composition and structure of space and form to be discovered simultaneously and relationally with the phenomena of color and kinetics, to generate and visualize an idea as form, and to represent form as experience. This requires interweaving computing with a creative process in which percept, rather than precept, is the driving force of the investigation. This paper explores the role of ideation, tectonic color and kinetics as an intentional design strategy and formgiver for architecture. The role of the computer is to enable the designer to generate meaningful architecture beyond precepts of image and style. Design as a making in the mind uses our rational and imaginative faculties. Complete freedom is not a necessity for inventiveness. Research on creativity indicates that "constraining options and focusing thought in a specific, rigorous and discerning direction" play an important role. The key is a balance of structured and discursive inquiry that encourages a speculative, free association of ideas. Tim Berners-Lee, one of the creators of the World Wide Web, likened creativity to a weblike process that is nonlinear but also not random; which when placed in an environment rich with information will float ideas so the mind "can jiggle them into an insight." Geoffrey Vickers in his essay, "Rationality and Intuition" described this symbiotic relationship as "...two functions which in practice are never wholly separated but which are, nonetheless, logically distinct as two reciprocating phases in a recurrent process of mental activity." The rational is formative and intuition is generative; both are essential to creativity.

title Computing and Problem Based Learning at Delft University of Technology Faculty of Architecture

summary Delft University of Technology, founded in 1842, is the oldest and largest technical university in the Netherlands. It provides education for more than 13,000 students in fifteen main subject areas. The Faculty of Architecture, Housing, Urban Design and Planning is one of the largest faculties of the DUT with some 2000 students and over 500 staff members. The course of study takes four academic years: a first year (Propaedeuse) and a further three years (Doctoraal) leading to the "ingenieur" qualification. The basic course material is delivered in the first two years and is taken by all students. The third and fourth years consist of a smaller number of compulsory subjects in each of the department's specialist areas together with a wide range of option choices. The five main subject areas the students may choose from for their specialisation are Architecture, Building and Project Management, Building Technology, Urban Design and Planning, and Housing.

The curriculum of the Faculty has been radically revised over the last two years and is now based on the concept of "Problem-Based Learning". The subject matter taught is divided thematically into specific issues that are taught in six week blocks. The vehicles for these blocks are specially selected and adapted case studies prepared by teams of staff members. These provide a focus for integrating specialist subjects around a studio based design theme. In the case of second year this studio is largely computer-based: many drawings are produced by computer and several specially written computer applications are used in association with the specialist inputs.

This paper describes the "block structure" used in second year, giving examples of the special computer programs used, but also raises a number of broader educational issues. Introduction of the block system arose as a method of curriculum integration in response to difficulties emerging from the independent functioning of strong discipline areas in the traditional work groups. The need for a greater level of selfdirected learning was recognised as opposed to the "passive information model" of student learning in which the students are seen as empty vessels to be filled with knowledge - which they are then usually unable to apply in design related contexts in the studio. Furthermore, the value of electives had been questioned: whilst enabling some diversity of choice, they may also be seen as diverting attention and resources from the real problems of teaching architecture.

summary This work highlights the application of GIS in the registration of resources identified as the environmental heritage of urban areas. To begin with, a brief description of the data collection method, based on local communities’ perception, is provided. It is maintained that the consideration of social values attributed by the population results in a more legitimate spatial knowledge, allowing for the identification of the more relevant elements, according to local inhabitants' statements. Finally, an emphasis is given to data processing techniques, asserting that the use of computer aided tools can ease the diffusion of knowledge about the society’s environmental heritage. This, in turn, may activate the recollection - and the preservation - of the cultural memory and, eventually, the formulation of strategies for recovering built heritage. It also opens the way to expand upon political conscience and social participation, enlarging the concept of citizenship.

title On the Translation of Design Data into Design Form in Evolutionary Design
source International Conference on Generative Art
summary The marriage of advanced computational methods and new manufacturing technologies give rise to new paradigms in design process and execution. Specifically, the research concerns itself with the application of Generative and Evolutionary computation to the production of mass-customized products and building components. The work is based on the premise that CAD-CAM should evolve into a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customized designs that exhibit common features. The concept of Parametric Design is well established, and chiefly concerns itself with generating design sets that exists within the boundaries of pre-set parametric values. Evolutionary Design extends the notion of parametric control by using rule-based generative algorithms to evolve common families of individual design solutions. These can be optimized according to particular criteria, or can form a wide variety of hierarchically related design solutions, while supporting design intuition. The integration of Evolutionary Design with CAD-CAM, in particular the areas of flexible manufacturing and mass-customization, creates a unique scenario which exploits the full power of both approaches to create a new design-process paradigm that can generate limitless possibilities in a non-deterministic manner within a variable search-space of possible solutions.This paper concerns itself with the technical and philosophical aspects of the codification, generation and translation of data within the evolutionary-parametric design process. The efficiency and relevance of different methods for treating design data form the most fundamental aspect within the realm of CAD/CAM and are crucial to the successful implementation of Evolutionary Design mechanisms. This begins at the level of seeding and progresses through the entire evolutionary sequence, including the codification for evaluation criteria. Furthermore, the integration of digital design mechanisms with CAM and CNC technologies requires further translation of data into manufacturable formats. This paper examines different methods available to system designers and discussed their effect on new paradigms of digital design methods.

summary The feasibility of a proposed CAD project is often judged in terms of two conceptions of complexity: design complexity, based on visible features of the object to be modeled; and CAD complexity, based on the actual CAD embodiment of the design. The latter is suggested as a more useful guide. Clearer articulation of this underutilized concept is proposed for use in both educational and industrial settings. A formal model of CAD complexity is introduced, and initial experiments to determine the complexity of CAD models are described.

summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

summary Our collective concept of computing and its relevance to architecture has undergone dramatic shifts in emphasis. A review of popular texts from the past reveals the biases and emphases that were current. In the seventies, architectural computing was generally seen as an elective for data processing specialists. In the early eighties, personal computers and commercial CAD systems were widely adopted. Architectural computing diverged from the "batch" world into the "interactive" world. As personal computing matured, introductory architectural computing courses turned away from a foundation in programming toward instruction in CAD software. By the late eighties, Graphic User Interfaces and windowing operating systems had appeared, leading to a profusion of architecturally relevant applications that needed to be addressed in introductory computing. The introduction of desktop 3D modeling in the early nineties led to increased emphasis upon rendering and animation. The past few years have added new emphases, particularly in the area of network communications, the World Wide Web and Virtual Design Studios. On the horizon are topics of electronic commerce and knowledge markets. This paper reviews these past and current trends and presents an outline for an introductory computing course that is relevant to the year 2000.

title Swarm modelling. The use of Swarm Intelligence to generate architectural form
source International Conference on Generative Art
summary .neither the human purposes nor the architect's method are fully known in advance. Consequently, if this interpretation of the architectural problem situation is accepted, any problem-solving technique that relies on explicit problem definition, on distinct goal orientation, on data collection, or even on non-adaptive algorithms will distort the design process and the human purposes involved.' Stanford Anderson, "Problem-Solving and Problem-Worrying". The works concentrates in the use of the computer as a perceptive device, a sort of virtual hand or "sense", capable of prompting an environment. From a set of data that conforms the environment (in this case the geometrical representation of the form of the site) this perceptive device is capable of differentiating and generating distinct patterns in its behavior, patterns that an observer has to interpret as meaningful information. As Nicholas Negroponte explains referring to the project GROPE in his Architecture Machine: 'In contrast to describing criteria and asking the machine to generate physical form, this exercise focuses on generating criteria from physical form.' 'The onlooking human or architecture machine observes what is "interesting" by observing GROPE's behavior rather than by receiving the testimony that this or that is "interesting".' The swarm as a learning device. In this case the work implements a Swarm as a perceptive device. Swarms constitute a paradigm of parallel systems: a multitude of simple individuals aggregate in colonies or groups, giving rise to collaborative behaviors. The individual sensors can't learn, but the swarm as a system can evolve in to more stable states. These states generate distinct patterns, a result of the inner mechanics of the swarm and of the particularities of the environment. The dynamics of the system allows it to learn and adapt to the environment; information is stored in the speed of the sensors (the more collisions, the slower) that acts as a memory. The speed increases in the absence of collisions and so providing the system with the ability to forget, indispensable for differentiation of information and emergence of patterns. The swarm is both a perceptive and a spatial phenomenon. For being able to Interact with an environment an observer requires some sort of embodiment. In the case of the swarm, its algorithms for moving, collision detection, and swarm mechanics conform its perceptive body. The way this body interacts with its environment in the process of learning and differentiation of spatial patterns constitutes also a spatial phenomenon. The enactive space of the Swarm. Enaction, a concept developed by Maturana and Varela for the description of perception in biological terms, is the understanding of perception as the result of the structural coupling of an environment and an observer. Enaction does not address cognition in the currently conventional sense as an internal manipulation of extrinsic 'information' or 'signals', but as the relation between environment and observer and the blurring of their identities. Thus, the space generated by the swarm is an enactive space, a space without explicit description, and an invention of the swarm-environment structural coupling. If we consider a gestalt as 'Some property -such as roundness- common to a set of sense data and appreciated by organisms or artefacts' (Gordon Pask), the swarm is also able to differentiate space 'gestalts' or spaces of some characteristics, such as 'narrowness', or 'fluidness' etc. Implicit surfaces and the wrapping algorithm. One of the many ways of describing this space is through the use of implicit surfaces. An implicit surface may be imagined as an infinitesimally thin band of some measurable quantity such as color, density, temperature, pressure, etc. Thus, an implicit surface consists of those points in three-space that satisfy some particular requirement. This allows as to wrap the regions of space where a difference of quantity has been produced, enclosing the spaces in which some particular events in the history of the Swarm have occurred. The wrapping method allows complex topologies, such as manifoldness in one continuous surface. It is possible to transform the information generated by the swarm in to a landscape that is the result of the particular reading of the site by the swarm. Working in real time. Because of the complex nature of the machine, the only possible way to evaluate the resulting behavior is in real time. For this purpose specific applications had to be developed, using OpenGL for the Windows programming environment. The package consisted on translators from DXF format to a specific format used by these applications and viceversa, the Swarm "engine", a simulated parallel environment, and the Wrapping programs, to generate the implicit surfaces. Different versions of each had been produced, in different stages of development of the work.

title The Management and Visualisation of Document Collections Using Formal Concept Analysis
source Griffith University, Australia
summary This thesis proposes a methodology, notation/theory, and software framework for organising documents using formal concept analysis. The documents are organised for the purposes of retrieval and analysis using background information in the form of a taxonomy of terms. An emphasis is placed on the development of a methodology that employs scalable computer programs to assist humans in the process of organisation, retrieval and analysis of document collections.The text retrieval community has also been concerned with the organisation of documents. The work outlined in this thesis makes use of the results of the text retrieval community at its lowest layer. Above this layer formal concept analysis is used as a mechanism to allow users to organise document collections using views determined by small numbers of attributes. These views, also known as scales, can make a mixture of coarse and speci c distinctions between documents, and are either selected or created by the users to make precisely the distinctions between documents that are important to their current tasks.The primary tool for the presentation of the results of formal concept analysis is a line diagram. The e ectiveness of the presentation of information contained in a line diagram is heavily dependent on the quality of the diagram. To support users in arriving at a quality diagram for a newly created view, graph drawing algorithms are adapted to the special case of determining a good layout for a concept lattice. This task is di erent from traditional graph layout problems because lattices exhibit a high degree of structure which should be exploited and made evident in the nal diagram. A new layout algorithm is proposed that combines a layered diagram approach and an additive diagram methodology. This new hybrid algorithm is shown to produce better diagrams than other adapted graph drawing algorithms.

title Graficacion, Virtualidad y Computadoras (Graphics, Potentiality and Computers)
source SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 277-279
summary The different approaches to virtuality in connection with graphical representation is the main theme of this paper. In the first part, the trends of global civilization are seen as a kind of over valuation of processes in progress. In this sense action itself is more important than things. The way as means have substituted the ends is discussed. In this context the role played by images as vehicles going between things creates the need of graphical objects. Following this, the meaning of “graphics” in connection with the different planes of virtuality are discussed. In the same way the concept of “virtual space” is examined. It is shown that the notion of “space” is hard to grasp if an attempt of rigorous definition is made. Finally, a discussion about the graphical representation of architectural space leads to some conclusions on the action of computers as instances of a new kind of virtuality: that which deals with objects without touching them.

title Resource-Adaptive 3D Maps for Location Based Services
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.29-I.38
summary In this paper, we present a database driven approach for managing and visualizing 3D urban city models and related multimedia content. Such a 3D database is a core component of a 3D Cadastre system (Coors 2002a). In the TellMaris project (IST 2000- 28249, www.tellmaris.com), we will make use of the 3D database to generate 3D maps. The objective of TellMaris is the development of a generic 3D-map interface to tourist information on mobile computers. The interface provides a new concept for creating value added information services on mobile computers for the European citizens related to geographical information. The interface is in the project used for accessing tourist information relevant for boat tourism in the Baltic Sea and Aegean Sea area in the Mediterranean. In this paper we focus on the online generation and compression of 3D-maps in order to make use of these maps in a mobile enviroment.

title Architectural Innovation as an evolutionary process
source International Conference on Generative Art
summary Traditionally in art and architectural history, innovation is treated as a history of ideas of individuals (pioneers), movements and schools. The monograph is in that context one of the most used forms of scientific exercise. History of architecture is then mostly seen as a succession of dominant architectural paradigms imposed by great architectural creators fighting at the beginning against mainstream establishment until they themselves come to be recognised. However, there have been attempts to place architectural innovation and creativity in an evolutionary perspective. Charles Jencks for example, has described the evolution of architectural and art movements according to a diagram inspired by ecological models. Philip Steadman, in his book "The Evolution of Designs. Biological analogy in architecture and the applied arts" (1979), sketches the history of various biological analogies and their impact on architectural theory: the organic, classificatory, anatomical, ecological and Darwinian or evolutionary analogies. This last analogy "explains the design of useful objects and buildings, particularly in primitive society and in the craft tradition, in terms of a sequence of repeated copyings (corresponding to inheritance), with small changes made at each stage ('variations'), which are then subjected to a testing process when the object is put into use ('selection')." However, Steadman has confined his study to a literature survey as the basis of a history of ideas. Since this pioneering work, new developments like Dawkins' concept of memes allow further steps in the field of cultural evolution of architectural innovation. The application of the concept of memes to architectural design has been put forward in a preceding "Generative Art" conference (Daru, 1999), showing its application in a pilot study on the analysis of projects of and by architectural students. This first empirical study is now followed by a study of 'real life' architectural practice. The case taken has a double implication for the evolutionary analogy. It takes a specific architectural innovative concept as a 'meme' and develops the analysis of the trajectory of this meme in the individual context of the designer and at large. At the same time, the architect involved (Eric Vreedenburgh, Archipel Ontwerpers) is knowledgeable about the theory of memetic evolution and is applying a computer tool (called 'Artificial') together with Remko Scha, the authoring computer scientist of the program who collaborates frequently with artists and architects. This case study (the penthouse in Dutch town planning and the application of 'Artificial') shall be discussed in the paper as presented. The theoretical and methodological problems of various models of diffusion of memes shall be discussed and a preliminary model shall be presented as a framework to account for not only Darwinian but also Lamarckian processes, and for individual as well as collective transmission, consumption and creative transformation of memes.
