Note that this "only" adds depth. It can't make anything appear to "come out of" the screen, the effect is more like a window. It's not like holograms in science fiction.
It's still pretty impressive tho.

Do you mean the effect doesn't work with back to front motion? Like that pan can't start in the back and move forward?
That said, that's still basically "3D but without glasses", not exactly the Holodeck "hard light" future tech many people think of when they hear "real hologram".
That requires
1. The imagine coming "out" of the screen such that you can even see the image at 90º to the projector
2. The image occluding the physical background.
As far as I understand, such a thing is impossible as seen in the still above (i.e. from a single projector), but can be fakes by using stuff in the air to scatter the light, like this research project (1) or this not-great version that uses fog (2)

This means 3d impression works even for people with reduced stereoscopic eyesight, and does not create headaches due to a mismatch of scene depth vs. physical display depth.
Such holographic displays do exist, e.g. www.seereal.com (which BTW recently received an investment by Volkswagen).
For a "low tech" example of such effects take a look at http://amasci.com/amateur/holohint.html and related content.
