The DSi seems to be getting all the cool mods and appendages these days, so we're pleased to see the other portable Nintendo gaming system getting some love. We've tracked down video of an Arduino-powered touchscreen hack for the Game Boy Advance SP that brings to life one of Nintendo's own concepts and -- while not quite on par with the GamePack -- comes with all the exposed hardware and blinking lights you'd expect from a quality mod. Though there's no interface or game compatibility to speak of, the coolness factor alone should be enough for you to check out the video after the break.
