From My Cold Dead Hand!

Prof. Yosi Shacham-Diamand of Tel Aviv University's Department of Engineering, working with a team of EU scientists, has successfully wired an artificial hand to existing nerve endings in the stump of a severed arm. The device, called "SmartHand," resembles ― in function, sensitivity and appearance ― a real hand. They fell a little short on the appearance point, but otherwise this sounds like the culmination of years of work in this field.

Now that they've got the hand part down there's only 1999 parts left to go.
