That's what I was going to link to.

Also, I made some student code a similar game a few years ago, cf my web page [1]. Except the game was played over IRC (the code was an IRC bot). They had a working implementation in Racket and it was quite fun to play with. I don't think they released it however :-/.

EDIT: Actually I just asked and they did release it! But it's on Gitorious [2]…
