Here's a video of a Christmas light setup syncronized to music. Apparently the score is Trans-Siberian Orchestra's Christmas Eve Sarajevo and the lights do a pretty good job of accenting the music. Not all of the lights are set to the music as some of the front white lights on the left and right side of the setup are not syncronized. The real question is does this guy have that thing going on the entire time or he only setup the syncronization to record it. It probably drives the neighbors nuts if it repeats over and over like that the whole time for a month.
