Apparently, someone REALLY likes Xmas light displays. (article, with a link to the WMV video clip). If the video link doesn't work, try this one. Keep trying 'til you get it...you will need sound, and about 3 minutes of uninterrupted "fuck, I'm IMPRESSED" time.
And, for those that get curious, the song is "Wizards in Winter" by the inimitable Trans-Siberian Orchestra.
Just amazingly cool.
