New coding contest

We haven't had one in a while so let's have a new coding contest. I'm open to suggestions for the challenge, but if we don't have any good suggestions we will default to something stupid like "implement cowsay in erlang shitty language X".

I will not do anything involving tetris, fibs or pong. I might write a mud server. However, I will, in the spirit of this thread, write something I otherwise wouldn't have by Monday at 00:00 EST. (I may or may not post it here.)
