To 500,000 (!) musically-synchronized lights ...
You really need to watch this in full screen.
From the notes about how they made it:
This was really filmed in the middle of the night, as you may have guessed.
500,000 Christmas lights “starred” in this display (that’s a half-million, people!!)
4,900 digital channels were utilized to ensure that the entire spectrum of the piano’s keyboard was featured brilliantly.
46,000 watts of juice were pumped to electrify this pizazz!
A camera attached to a drone served as the primary angle to capture the captivating Christmas Spirit of these festive homes.
The piano was actually being played.
The police actually did show up. For real. (We’d like to thank them for their kindness and mercy.
No pianists were harmed or jailed in the making of this video.
I love this. Go ahead - turn it up and bother the neighbors!
