Waking up from a nightmare in which stackable mecha roll of the decks of futuristic, space-borne aircraft carriers capable of punching holes through planets and do battle all Robotech-style against hordes of invaders in period-correct Zeros that transform into dancing robots, we popped on the internets and found this post. Apparently, Frank Gehry's teamed up with the whizzies at the MIT Smart Cities Group to come up with a futuristic electric vehicle (to be built by GM) whose most salient feature is that it's shopping-cart stackable. And vaguely mecha-esque. Scary. Weird. Rethink.
