One is invisible / see through clothing, which uses a camera / projector setup to make it look as though the cape is transparent (I’ve seen many blogs referring to this as the real thing ie. bending light around the cape or the back being made up of camera’s and the front of display, but they obviously failed to go to the source and check up to see that it’s really clever trickery).
They also dive into telepresence or telexistence, where they project people onto robots to make it seem like they’re there.
They have a space age futuristic head mounted projector, which just looks far out.
There are plenty of movies on the site to illustrate better what they’re doing – it’s very convincing indeed.
