Some computer programs give the user the choice to work either with the graphic objects appearing on the screen, or with the scripts which define and generate them, or with a combination of both. I consider this a powerful concept and specifically interesting for designers. On the background of my own explorations, I offer to help learning how to build parametric objects with the Geometric Description Language (GDL) in Graphisoft ArchiCAD, and how to generate and manipulate movies with ActionScript in Macromedia Flash. We will either explore forms with curved edges and surfaces in 2D and 3D, or experiment with implementations of ideas relating to interactive drawings.
