Karl Sims

I like his stuff. Check out Genetic Images, 1993 by Karl Sims:

Genetic Images is a media installation in which visitors can interactively "evolve" abstract still images. A supercomputer generates and displays 16 images on an arc of screens. Visitors stand on sensors in front of the most aesthetically pleasing images to select which nes will survive and reproduce to make the next generation

Here are some videos of his work with 3-D virtual creatures and motion graphics:





Impressive, especially given that this was almost twenty years ago.
