A friend asked me to give feedback on his coin changer kata. So I talked about a few things then showed how I might implement it.
Later I showed my roommate, and he suggested that the original had a good idea, and with a little refactoring could be even better than the OO solution. We sat down and did some refactoring and came up with vimeo.com/38732037 which is actually pretty nice.
Not sure which I prefer, guess we'll leave that up to the viewer :)

Hmm…it looks like things are taking a while to load. Try again?
