Bob Krawczyk, an architecture professor at Illinois Institute of Technology, specializes in new media art with a focus on algorithmic art to generate 2D and 3D art. Instead of brushes, paint, and canvas, he uses custom-designed software and his computer monitor and printer to create his art, and occasionally a laser-cutting machine and a fabrication shop to generate his 3D models. His BitArt website discusses the intricate models that he uses to generate his Escher-like geometric art. Krawczyk's related projects can be found here.
