Rockapella sings I Heard the Bells on Christmas Day

Christmas Lights 2009 - Rockapella sings I Heard the Bells on Christmas Day, one of five songs on my playlist for Christmas 2009. This year was my first stab at using Light-O-Rama software and hardware to control a Christmas light display. For this song, 32 circuits control about 4000 LED lights dancing in sync with the music.
