typetris

This was a lot like playing tetris. Stream of peices to fit into their type-holes. http://git.joeyh.name/?p=propellor.git;a=commitdiff;h=f35ef9d6975710f2d77c2ea708c66500861d92d1 237 lines in 30 minutes!
Must make a screencast of this kind of thing one day, but imagine me making the changes to the last 2 files in that diff, and then vim just takes me to type error after type error until the program is converted and ready for immediate deployment to a dozen machines.
