Interesting footage. Would have good applications for aircraft, as you would have to design any vehicle around it rather than retrofit existing things. Only obscures things a certain distance behind the lens, which means things such as fuel tanks and so forth would have to be offset (thus reducing massively operational range). Even then the attachment points would result in imperfect invisibility, unless you made it a sort of unibody thing where the skin is the frame.

This would make a sweet gimmick glass table.
