Skeletonics, a six-month-old Japanese student project, has resulted in an exoskeleton made of plastic and metal that's surprisingly dexterous and powered solely by the human embedded inside. As a bonus, the promo video looks something like a live-action Sonic the Hedgehog cutscene.

As the Skeletonics suit is unpowered, it doesn't grant any kind of crazy strength or Iron-Man-esque powers--the Skeletonics is mostly designed to extend the reach of a human's arms and legs, while keeping freedom of movement and dexterity. It looks like it succeeds at that, packing both working fingers that are delicate enough to hand candy to a child and spring-loaded legs that are capable of (hilariously) chasing a criminal through an underpass.
