Lambda the Ultimate

Following on the heels of this year's ICFP Programming Contest, Ant Wars is a competitive programming web game where competitors code finite state machine ant brains to guide colonies of ants. Two species compete for food in a simulation; the ant with the most food at the end winning.

The programming is currently done in an s-expression based high level language, compiled to a simple bytecode using SISC. Many intriguing behaviors have already arisen, including a running arms race between two competitors.
