RoboBeans is an interface to the "Robocup 2D Soccer Simulation Server" that allows developers to write Robocup teams\agents concentrating on behaviour and AI without having to worry about syntax of communication or network issues.
Project CodeRacers is a game geared for creative java programmers. It's main idea is that each player will create an own AI agent (the so-called "driver"). The user's driver then will compete against other players' drivers in a simulated car race.
