Looking Glass announces as $200 holographic display

I love this kind of screens because it has a physical volume that makes it believable that it's a real object inside a glass case.

Of course it's not immersive like VR, and doesn't augment the entire room like Hololens, but it doesn't require wearing special glasses, there is no friction to see the 3D effect. And it works for multiple people at the same time (unlike ones based on eye tracking) and it doesn't require you to be standing in front at a specific position (unlike stereo screens).

However the one limitation I had in the landscape version is the effect is only horizontal because it works like the lenticular printed holograms you'd get as a kid.

But for something that sits on your desk or in a storefront, you don't really look up and down the screen, so people don't notice that it's only horizontal.
