Here are some images I developed when creating some drawing behaviors in Processing.org.
Processing is a language a lot like java, only with a simplier structure and integrated drawing api that makes programmatic sketching possible. I have taught two workshops on processing at UBC, part of Julio Lopez’s graduate work to create a code/artist collaborative. His project was titled HUB Media Lab.
All of these images were created from code, using sampled color from another image. Most of the routines shown here were programmed with Object Oriented practices in mind. In essence, create an Object to do some drawing, make 6400 of them or more, and let them draw.
