Chris Anderson writes "This 5-min demo just posted from last week's TED — got a big crowd reaction. It's a new technology coming out of MIT, about to be commercialized. Siftables have been seen before, but not like this. They're toy blocks/tiles that are spatially aware and interact with each other in very cool ways. Initial use may be as toys, but there's big potential for new paradigm of spatially-aware physical mini computers."
