We really really wanted to see this system. It supposedly created a 3D projection in the air. They didn’t have a system on the floor, but invited us to their hotel room for a private showing. We did manage to find the room and were welcomed in to the sight of a smaller unit that made a roughly 4×4 inch projection inside a cylinder.
It was truly 3D. It was not the old angled glass trick. They would not let us take pictures, or video. The guy wouldn’t really answer any questions at all. We are speculating that it was just intersecting lasers. You could clearly see the vertexes, as you can see in the pictures above and there was a scanning refresh effect that was visible to the naked eye. We really wished we could have seen the big unit that projected into the air instead.
Edit: One of our readers managed to find a video of what we were talking about, thanks [alex]! Video after the break.
