Musician and Game Boy modding guru Joey Mariano has developed an eight headed, foot pedal monster that allows users to control the buttons of a Game Boy color with their feet. The sequencer hack processes the whole thing into an electronic orchestra of sorts, which could be quite impressive in the hands of a skilled musician.
You can even use macros for executing button combos on a single pedal for more unique sounds. Throw a guitar or a keyboard into your mix and you have the makings of one impressive musical experience. Just don't go overboard and start putting cymbals between your legs or something. [filefreakout via Nerd Arts via Make]
