This is unbelievably scary... You'd swear there was a person wandering around on stage in a robot suit; but it's not. It's a robot. And it plays the violin! http://www.geekalerts.com/toyota-unveils-two-new-robots/

wow... didnt some philosopher once say that the closer to being human robots get, up to the point where they are actually indistinguishable, the more unnerving they will be.. because they're ALMOST... but not QUITE... like us. Or something :D
