Generated Images
I've been experimenting with generating abstract images. The generating program uses a simple algorithm with many parameters: the creative process is an exploration of the possibilities in both the design of the algorithm and the settings of the parameters.
The design of the generating program allows me to create huge versions of these images at very high resolution. I think that large versions of these images (e.g. 4' by 6', or even "wall" size) could be engrossing.
