I took my son to see a light display that a guy in town set up as a fundraiser for a local non-profit. It's quite impressive in person, though this night he was outside working on something so it wasn't as flashy as normal as some of the arrays of lights were offline. He's got a low-power FM transmitter which is why you see the 89.3 sign at one point. You can tune your radio to it so you can hear the music the lights are programmed to "dance" to.
