That is pretty cool. I was just reading about the guy who got two bionic arms yesterday and I didn't know it happened 4 years ago. They mentioned bending at the elbow and wrists so I'm guessing they don't have any shoulder motions yet. As technology gets better I'm sure it'll only improve.
I thought it was pretty funny that the first thing she wanted to do was get nails put on them. Funny in the I think she's a little crazy context.
