Give Them a Hand
From: Servo Magazine - Bots in Brief - 11/2010 - page 22

Launched at the International Society for Prosthetics and Orthotics (ISPO) in
Leibzig, Germany by the UK-based company BeBionics, this myo-electric hand
fully integrates a wireless chip, 19 different silicone skin tones (so the
skin tone of the hand can easily blend in with the user), as well as fully
customizable functions to control speed, grip force, and grip pattern. It
supercedes past mechanical hands which were capable of flexion / extension
whereas this is reportedly capable of rotational articulation. 

This myo-electric hand is so sophistuaged that you can play piano with it,
play Jenga, and even do sign language. You can also grip various objects such
as a can of soda, a bouncy ball, and wooden blocks.
