Free image generating software

Hi All:
Ran across this a couple of days ago. Has some great possibilities for work, and play! Introducing the Evolvotron:

Downloads here:

This program's for Linux and Mac OS X users only.
I've posted examples below. Generates a window with 24 large thumbnail images to choose from. It's possible to take individual images through a number of "iterations". Selected images can then be saved as pngs, in any size from thumbnail through a 4000+ x 4000+ pixel image size.
Enjoy!
Scott
