ClaytronicsInteresting article about “Claytronics” or programmable matter – “The day when doctors routinely made house calls may be past, but that doesn’t mean that someday you won’t routinely see your doctor in your home — with emphasis on “see.” That is to say, your doctor could physically work out of her office. But a three-dimensional lookalike, assembled from perhaps a billion tiny, BB-like robots, could be her stand-in in your home. She could talk with you, touch you, look at you, all under the control of the real, if distant, doc.” Link. Project page here.
