Of course it is very amazing and shows an advanced technology. But I don't believe that it as an "invisible veil" technology. We only see a displayed or reflected image of real objects transmitted from a recorded video or a hidden camera (perhaps on a Nano-Tech material as a display screen). Because for example:
In Tech1.mpe: The image of shelf is displayed upper than the real shelf.
In Tech2.mpe: Pause the video at 0:05:00 and compare the position of the displayed books with the position of real books on the shelf.
In Tech3.mpe: The front of the red truck is not seen at the correct position between 0:04:00 and 0:05:00.
In Tech4.mpe: The skull is not at the same position of the man's head between 0:17:00 and 0:24:00.
On the other hand the geometrical specifications of an object on a display screen depends on the position of at least 3 parametes: Object, Observer and Display Screen. Therefore only one observer can see a normal image on this screen.
