Hey everyone,
This is the link to a coding competition I just entered for my college. I just thought I'd post the link and see if anyone else felt like whipping something up, I'm interested to see where other people decide to go with this.
Here's my submission:

Which reads from this file:

(Before you criticize it, look at the point of the contest ;) )
Hope to see some other ideas!
