THE POETIC POTENTIAL OF COMPUTERS by Bennet Neiman and Ellen Yi-Luen Do A class that takes up the principles of Bauhaus Digital media are transforming the practice and teaching of design. Information technologies offer not only better production and rendering tools but also the ability to model, manipulate, and to understand designing in new ways. The Poetic Potential of Computers elective design seminar teaches students how to see, think, and form space using both digital and physical media. The course uses a systematic approach that follows the tradition of the Bauhaus principles of craftsmanship and visual perception. Precedents are drawn from the use of light, color and texture in the visual arts such as the glass collage assemblages of Josef Albers and Lazlo Moholy-Nagy’s camera-less photogram. References are also drawn from Wassily Kandinsky’s diagrammatic analysis of still life drawings and Gyorgy Kepes’s idea of the language of vision. The focus of the course is how digital media and physical material The design exercises represented offer a set of techniques for thin- can be used interchangeably as instruments in a design environ- king and creating through the computer that don’t exclude traditio- ment.

We use "analog" to refer to physical artifacts and 64 Arquitectura Digital Diseño Digital graph, a painting, or a pencil sketch, can represent the manipulation of objects in space. The play of transparency, superimposition, lines, colors, and light all contribute to a specific sense of space. Kepes further argued that one could derive visual awareness through the process of examining and making spatial configurations of objects. He also stressed the value of experimenting with artificial light sources to model the experience of an environment or a space.

Exercise 02 - Analog Spatial Manipulation Device: This exercise engages students in material management and photographic craftsmanship. Equipped with the analog space captures, each group creates a "spatial manipulation device" using transparent materials. The photographs (five from each space for a total of ten) are transferred to clear acetate films. Each group fabricates five, one-half inch thick acrylic panels that serve as armatures for the acetate images. They place acetate films on two sides of the acrylic panels, experimenting with the spatial concepts extracted from the photographs. The thickness of the acrylic creates a spatial quality that allows students to see images with overlapping planes. Images with spatial qualities are translated from photographic to transparent surfaces creating a conceptual space for media experimentation. In this exercise, design is the transformation and construction of instruments prepared for their roles in an analog performance. 66 3 6 4 Exercise 04 - Digital Performance: In a simultaneous imaging exercise, Exercise 07 - Radical Reconstruction: In this exercise, students use ima- two or more of the acetate films are directly overlaid into different combina- ge manipulation software to explore and enhance the spatial qualities of the tions.

In this exercise, design is the selective expansion of formal possibilities, through additive and subtractive processes. Exercise 11 - Digital Reliefs: Based on the digital templates, students make three-dimensional objects from the two-dimensional shapes. This exercise teaches students to construct a digital relief model by systematically applying thickness and height to different shapes in the flat templates. A digital projection of the templates transforms the exercise into a beginning three-dimensional study. The extrusion of linear forms provides a transitional study between the two-dimensional and three-dimensional worlds.In this exercise design is the creation of three-dimensional objects derived from analytical diagrammatic templates. Exercise 12 - Digital Spatial Manipulation Device: Once digital objects are created, their locations can be reconsidered. In this exercise, students use the modeling software as a "digital manipulation device" to explore variable locations of the digital reliefs in space. Space is accessed and re-evaluated through the intentional screen of a computer. Three unique model configurations are created as an interpretive transformation of the relief studies. For each model configuration, students generate a single one-point perspective view as a compressed series of spaces within spaces.
