Guitar Hero pedals for amputees

Portable console designer Ben Heck's latest project is a Guitar Hero hack that adds a useable floor pedal to the guitar controller. The pedal's most universal application is to allow you to use the whammy bar like a wa-wa pedal, but it also lets one-armed amputees play Guitar Hero by strumming with their foot. That's probably the way I'd use it too: as it is, it's hard to strum and keep your hand triumphantly aloft in a digital devil horns gesture.
