Imagine if drum kits didn't have kick drums. Music wouldn't be nearly as great! Here's how you can turn an old USB keyboard into a foot pedal and stomp stomp stomp your way through Google Reader (or whatever else).
OK, yes, I understand, you're not playing the drums with your fingers, so using your foot to control some function that could just as easily be triggered with a keyboard shortcut might not make sense on paper. But keyboard shortcuts are no fun. You know what's fun? STOMPING ON THINGS. Anyone who's played drums on Rock Band knows that. [BoingBoing]
