Amazon are apparently making a phone. With some kind of 3d thing going on. Involving 4 cameras on the front, working out where you are.
This doesn't actually make anything 3d.
What would be very cool is an invisible phone. This is entirely possible. It just requires the phone's display to show what's behind it - I.e. the view as seen by the camera on the back. This isn't terribly effective (despite the (dis) appearance of the Aston Martin "Vanish") unless the viewer, screen, and background are nicely aligned. But with the addition of eye tracking, a much more realistic "invisibility" effect can be produced by compensating for the change in viewing angles.
I really hope amazon have thought of that. I will find out in about 10 days.
(The point of an invisible phone is mainly just because it looks cool. But also you can then have text and graphics apparently floating in mid-air. Augmented reality that can actually be useful, like Google Glass.)
