Funkytown Keypad

My tribute to Towelie from South Park

This is basically a desk toy/paperweight that you can play tunes on using the keypad. If you play the right melody, it plays 4 different parts of the song Funkytown.

I don't know if anyone but me is crazy enough to want this, but I'm posting all the files (design files too) in case they are interested.
