Programming game

Ages ago (circa 2005) there was a game of some sort. It was played through the browser. It wasnt a game like you would think of, it was something involving programming. It was an IDE. I would swear it was Java or something really anal about formatting but I cannot for the life of me remember what it was. I know its very vague of a description but thats all I remember for sure. Oh, there was a leader board of some sort. I cannot remember the objective of the game though.

I figure someone here might know.

It would be cool, if the game involved designing an AI for Starcraft. Preferably in Lisp and with only input being the screen snapshots and output - mouse-clicks.
