I'm impressed . . .

According to the Daily What, Ric Turner, a former Disney 'imagineer' and special effects specialist, turned his yard into a game of Guitar Hero, built out of 21,268 lights and LEDs, that plays Eric Johnson's "Cliffs of Dover."
To program the show a video recording was made of a perfect round of Guitar Hero playing Eric Johnson's Cliffs of Dover. The timing of all the dots and the light show choreography follow that video.
When you play, you watch only the Christmas lights, but the audio you hear is from the Wii, so your flubs are broadcast for all to hear (people in cars can tune 99.1 and crank it up as loud as they want.)
