Looks nice, but this still has the one problem *all* artificial 3D has, and that is it's only parallax-based 3D. If I close one eye, I can still focus on near and far objects, but that's not possible with any current 3D system. I don't see anyone solving this problem for a long time to come.
Also, I have a problem with something that close to my eyes, since I wouldn't be able to focus too well on the screen.
Aside from those issues, it does look nice. I'm assuming he's managed to get the cost down by using recently-available off-the-shelf parts.
