On paper, it looks a lot like something from a video game. In actuality, it looks even more so. David Brown, a cameraman, editor and producer, has won a PopSci 2011 Invention Award for his BodyGuard design--an armored glove with a built-in stun gun, laser pointer, video camera and flashlight. Not only is the design lightweight and adaptable, it's also fully endorsed by Kevin Costner, a friend of Brown's who invested in BodyGuard (get it?). Get more details (and a video of Costner and Brown) on PopSci.
