Holographic TV!

Not very fast, though.

In the set up described in Nature, 16 cameras recorded 2D images of objects and people from multiple angles, and then sent that information to another location using a computer connection.

At the remote site, a laser was used to “print” the visual information on to the new photosensitive polymer. The 3D image composed of the 16 perspectives decays naturally, but the laser can write the next “frame” before it completely disappears.

The second (lower) video on the BBC page demonstrates the rewriting. There’s no demonstration of multicolor images, sadly.
