Out of bad things, good

Dean Kamens, already one of Rico's heroes because of his invention of the Segway, speaking at the TED conference (and, no, I didn't know about it, either) on his (or, more properly, DEKA, his team's) invention of a new prosthetic arm. A brilliant thing, though you'd expect no less from these guys, and a good thing for the human race. (Some things make Rico choke up, and this is one of them. If you don't, get a humanity check soon...)
