I used to be really into artificial life simulations. Here are some directories to tons of projects like that. You will need to use web archive for a good deal of this stuff though. And a recent update of Java seems to have broken a lot of the older web based ones. "Artificial life links": http://www.alcyone.com/max/links/alife.html http://www.alcyone.com/max/links/alife.html International Society for Artifical Life links page: http://alife.org/links.html http://alife.org/links.html Zooland Artificial Life links page: https://sites.google.com/site/myzooland/ https://sites.google.com/site/myzooland/ My favorite is Darwinbots, which has a lot more physics and features and things to tinker with than the average simulation. You can also directly program the bots to do whatever.
