This is the awsomest display of "dancing Christmas lights" I have seen. I like it better than the vids of Disney's that I've found. They synchronize everything perfectly, and they have different things personify different parts of the song.
Thanks to Cowboy for finding this! Dano loves it too -- he requests it about half as often as "Jingle Bells."
(Note to DKoren: it involves flashing strings of Christmas lights and parts of "The Nutcracker" played on metal instruments. You might hate it.)
