A selection of prosthetics sites. These prosthetics are controlled entirely by connection to the residual limb muscles of individuals who have undergone amputation. The prosthetic limbs use a combination of hydraulics, processors, and sensors to transmit information back up through the limb muscles to enable walking, running and other activities. (I love the applet on the Hanger site showing a man dancing, quite stylishly thank you, with a prosthetic leg.) These individuals in turn are the most likely to explore the frontier of neural prosthetics when that technology is ready to, if you will, take the next step.

For the human element, here’s the personal site of Cameron Clapp, a triple-amputee after being hit by a train. I challenge you not to be inspired.
