OK, I bow to popular opinion: almost 100 people have sent me a link to this story about a prosthetic tentacle. It’s a brilliant idea, but I don’t know anyone who has lost a limb who would suggest that their prosthesis is even an adequate alternative. It’s a little insensitive to swoon over one, then…but still, I like the idea of going outside the bounds of the human model to come up with a solution.

But I wouldn’t be satisfied until it had full sensorimotor integration and color-changing technology.
