First Post
Some full 3D projection schemes have been demonstrated, but the downside is that the laser brightness is usually up in the blindness-hazard or even burn-hazard range.
I can think of several things they might be doing here, thermal turbulence generation, ozone generation, maybe playing with non-linear optical properties of the air, but they all give me bad product liability vibes.
I think digital holography is probably going to beat out the death-ray projectors in the long run, though maybe they do have something safe and cheap enough to be practical.
