An MP3 player that recharges on the fly with no electricity required seems far fetched, but apparently you haven't thought about the power of the yo-yo. Yes, finally someone has combined an MP3 player with a yo-yo, giving you all the portable audio you crave with the boredom-dampening power of everyone's favorite childhood gimmick. It's not just a pretty face, however, as the yo-yo can actually be used to power the player. If the battery light comes on, simply give it a dozen tosses or so and you should be all set. Fortunately, it comes equipped with Bluetooth headphones, so you won't need to worry about ripping your headphones out of your ears by accident when trying to rejuice. Like most creative and unusual ideas, this one is pure concept, so who knows if it will ever see the light of day. — Adam Frucci
