So we all know technology is growing in leaps and bounds but really, a prosthetic hand designed after the one put on Luke Skywalker’s right arm after Darth Vader chopped it off with a light saber… I would not have believed it myself but check out the video below and see it in action for yourself. The hand used ultrasound technology to analyze contracting muscles in a person’s remaining limb and guess which finger they are trying to move. And yes he is playing the piano for the 1st time since loosing his hand 5 years ago.
