Check here for pictures and directions to Christmas light displays in Granbury, Texas.
I will include pictures of the display and a Google Maps link to get you there!
I have to start with myself (since I don't have anyone else's information yet).

Our Christmas Light display is synchronized to the music of six different songs. You can "Listen to the Lights" by tuning your car's FM Radio to 95.5 If you forget the number, don't worry, there is a sign in the yard to remind you.
This year we have approximately 20,000 lights on the house and in the yard. They are computer controlled on 80 independent channels. The controllers are made and sold by the D-Light company, located near Houston. The computer software is called Light-O-Rama. Think of it as a computer controlled Player Piano (if you remember such things).
