Wow, that was a rather interesting experience. I spend the last three days on testing the ICFP-contest. There is not much I can say about the actual content of the contest, but I can say that I learned several new things. Some of them are not so funny, while others are very cool!
Anyway, lets just say that our solution was not exactly optimal :) I am sure that other will do better. So if you have not done so, register here.
Have fun and hack away.
