holografisch-optische made in chemnitz. joint project with newsight to create a 3d projection system based on holographic principles. but: the image is only visible to one eye??

The image on the screen is only visible to one eye when the light of the projector hits the screen at a specific angle. Incoming light from other angles don't interfere with the image quality.|stereoscopy

3d white flashpoints for adhoc traffic signs and ads? laser display in thin air.

the display utilises an ionisation effect which occurs when a beam of laser light is focused to a point in air. The laser beam itself is invisible to the human eye but, if the intensity of the laser pulse exceeds a threshold, the air breaks down into glowing plasma that emits visible light.(new scientist)

improve lightweight near-to-the-eye displays and titled stereoscopic large size displays. (improve)

Hidden from public view at Super Bowl XL, spectacular live-action 3D holograms will be created from signals streaming in from networks of electronic eyes. These live-action holograms will help Homeland Security Agency officials detect people and objects suspected of endangering the 65 thousand ticket holders crowding into Ford Field, and the thousands more who will gather in downtown Detroit to celebrate the NFL's preeminent football contest.(stereoscopy

seems like it; no idea if it worked, though.
