Hey this guy was on the news.(second-hand info) He's a computer programer in Ohio. It takes him two months to set up 25,000 lights. The music is pumped out of an FM transmiter. and runs every night from 7-9pm. His electric bill goes up $250 a month.
Even though that was good, he is small potatoes compared to other Christmas people. Trush me, I know. let me show you a display that won last years PlanetChristmas contest. He got 750 for it. Anyway his website and video are below. I got to meet him last summer at the Chicago Mini-plus.
i had read about this guy, im pretty sure he used the thing, which its name escapes me, that they use to do fireworks....it has like 20 outlets on it and hooks in by USB or possible a parallel port and he used a C program to control current going to each of the outlets on it.
