Makey Makey + Ableton Live = Interactive Dance Floor

I made an interactive dance floor in my basement for a house party.

Technical note: When I said the Makey Makey has 18 "key press" connections, that was actually a simplification. Out of the box, some of the Makey Makey connections control the mouse. I reassigned all 18 connections using the Arduino programming environment. Instructions on how to do that are here: http://www.sparkfun.com/tutorials/388
