I want to let you know about a unique competition for Java programmers. It involves writing an AI controller to play randomly generated Super Mario Bros. levels. You will get a basic package of Java classes that you can use to test and play the game and write your controller around. You can enter the competition for free and win up to $500 if you can beat the other AI agents!
More information about this competition can be found at http://julian.togelius.com/mariocompetition2009/. I'm not affiliated with the organisation of the competition in any way.
It might be nice to set up a DC team and see what we can come up with...
