Well, we've seen a reassembling robot before, but that one was a chair, and, honestly, it's hard to get too frightened about a chair unless it's being swung at you by an unruly biker at the bar because you hit on his sister. Well these little reassembling robots are both scary and creepy (skip to around 1:26 for the good stuff). You kick them apart, and they find all the other pieces and self-assemble. Just think of the possibilities.
How would you like to have your very own shape-shifter? Perhaps a liquid metal T-1000 Terminator to help around the house. Or a universal tool kit that could reshape itself into any implement at the press of a button.
Okay, any mention of robots that includes a reference to "shape-shifters" and the Terminator is bound to scare the shit out of me. Needless to say I'm writing this from under my parents' bed. Speaking of which, there's an awful lot of damn squeaking going on up there. Oh no. Oh God, no.
