Holographic Displays and displays everywhere

Hologram technology today has advanced dramatically since a decade ago. True 3D images used only to be possible by lighting real objects with lasers, but now it's possible to create super fine-detail full-colour holograms from computer models.

The following video shows a city-scape originally sketched up in google sketch-up and converted into a full colour hologram.

However, this image is still only 3D, the World Wall used by Needle in The Looking Glass Club, is a gigapixel per square centimetre dynamic 4D holographic display (the extra dimension being time). Well, breakthroughs in rewritable holographic media mean that real-time holographic displays are now capable of generating a frame rate of about 15 frames per second and the technologies are advancing all the time. They may not look terribly hi fidelity today, but it's only a matter of years before true 3D holographic TV is a reality.

Display technology is getting cheaper and more flexible all the time too. There are already examples of cloth displays (foldable and wearable), but even simpler technologies are being combined to make some fascinating new applications. Take a look at this Japanese invention from back in 2003 which combines photoreflective material (like the high relfective stuff found on bicycle jackets) and a camera and projector system. The result is a quasi-invisibilty cloak!

Okay, so it's not quite Harry Potter, but it's a marvel to watch!
