The USB Electrical Muscle Stimulation mouse
Cancel your gym membership (or at least pretend you had one in the first place), because Rare Mono has solved all of your problems with the Kinniku Mouse, a USB mouse that promises a workout while you work. You just connect the electrodes to the mouse, attach them to the muscle group you want worked, and kick back and watch the twitchy wonder that is Electrical Muscle Stimulation do its business.
P.S. - Japan is now officially freaking us out.
