John Storms of Austin, Texas, told Huffington Post that he and his family have been planning these holiday light displays since 2010, synchronized with popular music. The "Let It Go"-themed display has allegedly been in the works since February, so it's a good thing the movie is still relevant, the song forever seared into our collective mind.
He said the display runs on LED lights and that the "computer that runs the show is an energy efficient netbook that also keeps the power usage down."
