B.O.T.S.. A C-Robot style sim. Similar to Darwinbots in many ways.
I'm probably going to scour their source code to see how they did some things, what sorts of speed they're getting, etc.
I haven't looket at it yet (I'm in the library, totally can't install :(). If anyone sees anything in it that's cool that DB doesn't have, we should totally add it! It mentions some bot debuggers, etc.
