Here’s Ben Heckendorn’s latest invention. It’s a pedal for Guitar Hero (and presumably Rock Band) that controls the strumming and whammy bar functions, so people with only one good arm (and presumably chronic masturbators) can rock out like everyone else. Heckendorn built the pedal for the Games for Health conference.

These replace the strum and whammy bar from a standard guitar, allowing you to use a single hand for the chords. What you do is use your foot and click your toes up or down to strum or navigate menus. To perform a whammy you lift up your heel…The pedal plugs into a modified Guitar Hero 3 Les Paul wireless controller. You can still strum the modified guitar but the whammy is only on the pedal.

Pretty cool. The cable from the pedal to the guitar is from an Atari Jaguar, too. Nice.
