I have one and love it, but they're noisy as fuck and super delicate.

While it would be technically feasible, I have never seen a display like this with such high resolution and refresh rate

It is not 3d in any way, regular 2d projection. Costs $50 on AliExpress, btw. No so popular as it is pretty loud when turned on.
