They has arrived. Albeit solid ones that you cannot touch, but still!

I watched it, and although I didn't understand half of what they were saying, it looks interesting. :)

Notice the plexiglass cube - that's a ballistics shield in case the glass mirror shatters while spinning at 1.2k RPM !

The displayed image is rendered one frame for every 1.25 degree of horizontal rotation around the model and projected in sync with the spinning mirror.  To achieve a reasonable perceived frame rate the projector (and rendering software) must run at 5760fps.

The spinning mirror allows natural parallax (changes in the image relative to observer position) around the axis of spin only.  Vertical parallax has to be done via eyepoint tracking, feeding a different set of rotation images to the projector depending on the viewer's elevation.  The adjusted image would only look correct to the tracked observer - to everyone else the image would appear to flip in place.

Colors and image complexity can be increased with better projectors and rendering software.

Spinning hyper-death-glass holoprojectors will not be invited to my living room, though.
