We saw the glow of this Omaha, Nebraska display from West bound I-80 between the
60th and 72nd St exits and had to investigate. The music was broadcast via low power FM, You might be able to pick it up on that stretch of interstate on 103.9
It's kitschy, commercialized, over the top , off the hook, a crazy chaos of noise and light, and completely addictive.
There are more of these syncronized displays on YouTube and at www.Lightorama.com
Here's a fun one, Boogie Woogie Santa.
