I saw an earlier prototype at a Demosplash at CMU. It was
really incredibly cool in certain instances. 3D objects really looked like they were "in" the volume of the display and moving my body or head from side-to-side was pretty flawless.
That being said, it also had limitations. 3D effects that extended beyond the display (like a tunnel, or some larger effect) lost that depth to me, and there's no up-down 3D, only side-to-side. The one I saw was also not as high-resolution as you might think, the effective resolution was the resolution/elements where each element was a particular angle the display was to be viewed from and the computer had to render the display from each angle simultaneously. The prototype I saw had the effect of looking a bit like 3d objects underwater.
Still, it was the closest thing I've seen to a volumetric display outside of a lab, and in the cases where it really worked (things inside the volume of the display) it was kind of jaw dropping.
edit here's the pouet page for the demo I saw

This video is from a handheld camera that moves around the display that's helpful to understand how it works https://www.youtube.com/watch?v=US7hzM0a21E&feature=youtu.be
