Another arrangement on the same house, with Jingle Bells audio by (brace yourself) Barbra Streisand: 2-minute video (Windows Media)
(Users of better operating systems can view Windows Media video using the open-source video player VideoLan (a.k.a. VLC).)
The light arrangements are by Carson Williams on his Mason, OH house. The show ran four hours a night at low volume, simulcast via low-power FM radio for drive-bys, and used 16,000 lights and the Light-O-Rama sequencer.
Or, play Pong on the side of an office building using your cell phone.
(Thanks to Barrett Golding and others for more info!)
UPDATE 12/5/05: How to make the EXACT same display on your own house using Carson Williams' sequencer file.
Yet another UPDATE 12/8/05: Williams has pulled the plug on the light show at his house, due to traffic problems and accidents in front of his house.
