Though patents often never amount to anything, we sincerely hope this wacky one from Samsung does. It's an approved idea for a portable music player that also contains keys and motion detectors to let it function as a "musical instrument," too. While listening to that epic jam, you could play along by pressing keys on the side of the device as if you were fingering a guitar's fretboard. You'd be able to change position on the "guitar neck" by moving the player back and forth, and a motion detector on the side would sense the fingers on your other hand as you strum chords or pluck out a solo. Your GarageBand-style noodling, along with the original music would all blare through a speaker and amp combo on the device, to the amusement / horror of your friends. That's assuming Samsung ever builds one, of course -- but if not, our John Q. Engadget will be the first name on a petition to get it to market.
