This isn't the first time Christmas lights have met Guitar Hero on the pages of Gizmodo, but this former Disney employee's efforts are definitely the best use of the game that I've ever seen.
Using 21,268 lights and LEDs, ex-Disney imagineer and special-effects specialist Ric Turner turned the front of his house into the perfect setting for a Guitar Hero Christmas lights spectacular.
As he explains:
Christmas Light Hero is using 7 light controllers from Light-O-Rama built from kits to control 21,268 lights and LEDs. Each controller has 16 outputs and 2-3 TTL level control inputs that are used by the game system to fire different programmed light sequences depending on what happens in the game. It relies on the fact that the game sequence is very consistent. If the game and the lighting sequences start together, they will stay in very good sync through the length of the song. The light program allows branching and overlays for fail, star power and "ready." I have some ideas to automate the initial show/game sync, but for now you have to push doorbell buttons at the right moments.
