Possibly - but even if it is a fake, it still excites me because I'd never considered the possibilities of an interface like that before. Only in a vague, background, never really examined way while using something like Photoshop - "wouldn't it be great if I could just grab that thing and pinch it smaller?" - but I never took the thought far enough into the territory of "what sort of interface would you need to do that?"

But now someone has thought about it, even if they haven't actually built it. That's enough :)
