This screensaver lets you watch Continuum spaceships evolve from being absolutely stupid to fighting fiercely for "greens". Only the ships eating enough greens will survive long enough to "reproduce".
The project started as my first experiment in artificial intelligence. It uses neural networks trained by a genetic algorithm with some simple dynamic learning. You can read more about this on the A.I. description page.
You get some control over what is going on in the "world", but you have no control over any individual ship. In particular, you can change how many greens are available (e.g. to starve the ships to death). You can load and save the genome that has evolved, and you can adjust some A.I. learning parameters.
