A couple of days ago while trying to stay awake while my simulations ran for hours, I came across this website: Electric Sheep. It seems like a really cool idea. It is a “distributed screensaver” that makes use of genetic algorithms to progress and improve itself. If the people who are using the screensaver press a button they can rate the screensaver good. This is then used as part of the fitness function in the genetic algorithm allowing the good screensavers to be carried along into the next generations.
