C'mon, be honest -- the unofficial cutoff age for playing with Legos sans kids is sometime way before puberty, but thanks to a new development from Carnegie Mellon University, we adults may soon be able to unashamedly indulge in those desires once more. Posey, hailed as a "hands-on way of interacting with computers," features a plethora of snap-together, sensor-laden parts that can communicate with PCs through ZigBee. When a user attaches a leg to a body, for instance, an on-screen representation immediately mimics the movement, providing hours of fun and some real promise for future applications. No word on whether these things are set to go commercial anytime soon, but we'd sure love to replace this aging (and seemingly busted) voodoo doll with one of these critters, pronto.
