My tech teacher showed us this today. This guy's programmed his Christmas lights to "dance" along with music. He even put the music on an FM transmitter to put on the radio, rather than using loudspeakers. Unfortunately, the city made him shut them down because of the traffic that was building up in front of his house. Miller (The beer company) even spent a week filming it for a commercial. http://www.dailymotion.com/elemmaciltur/video/9941 I want to do that with Pull Harder on the Strings of Your Martyr.
