The Pixel Combiner - Specify your parameters, and watch it generate all possible pixel combinations for you
Version: 1.00I've already written this up much better in my journal.
Operating System: Mac OS X
So hop over there. You can also download the C and perl source, if you'd like. Or just run the objective C version here. Complete with screen saver. :)
No, it will never ever ever generate anything even remotely interesting. Sorry. Maybe the G5'll have enough power to generate something cool.
You may either run it as a stand alone app, or run the screen saver edition.
