Here's a little Holiday fun from former Disney Cast Member Ric Turner (he worked in special effects which I'm sure you'll have no trouble believing when you see the video). Mr. Turner hooked up his Guitar Hero game to his light display the results of which you can see below (be sure to watch the very end).
You can actually play the game, say's Mr. Turner; "Even though the game is in "easy" mode, the lights don't provide the same timing detail as the game does, so it is much harder. Even expert Guitar Hero players have a hard time with the lights, and nobody has made it through without errors (yet)."
