Cute boy. Fake arm.

The iLimb is a new prosthetic arm that looks, feels, and acts like a real human limb. It was developed by a Scottish company, Touch Bionics. It's already won Time Magazine's invention of the year 2008.
The boy in this video, Evan Reynolds, 19, had his arm amputated after a car accident in a parking lot with a friend. The new arm is pretty amazing. It can grip like a real hand, and is controlled by the wearer's brain, so all they have to do is think about moving and it responds.
