That Sony video was produced as an ad for the Playstation Video Store, in a studio. It's not even remotely the same. It also requires acting from the participant (the guy isn't -really- seeing a floating cube. He can't see it at all), and a bunch of stagehands in full-body white suits moving props and furniture around in your living room. Anyone even suggesting it's the same thing is either insane or deliberately trying to be a negative nancy.
Anyway, it looks awesome. I wonder what kind of projector they're envisioning for this in a consumer product, and where it would be positioned.
I also want to see a C9 video about this.
