I tell ya. If I had the talent, the time, the patience, the talent, the vision, and/or the talent to do something like this? I still probably wouldn't do it because of how...ridiculously difficult it must have been to accomplish.
Take a look at this video of a Halloween lights display synched up to the theme song from The Nightmare Before Christmas. It's probably the coolest thing I've seen all Halloween season.
And be sure to check out the designer's YouTube channel for more incredible displays.
