Process Compendium
Casey REAS is one of the two original creators of Processing. As such, he’s been pretty influential in the generative art space.
Process Compendium 2004-2010 is a catalog of generative artworks. Each piece, which Casey calls a “Process”, is a short description, in English, of a kinetic drawing machine. The implementation in software is up to the programmer’s interpretation. The history of the ongoing project is quite interesting, recounting a series of works that build up processes from basic forms, behaviors, and elements.
Here’s a video introduction to the Process works. If you want a step-by-step walkthrough of the project, this is probably the best place to get it.
