Fog projectors have been around for ages, but projecting a 2D image onto a wavy field of 3D smoke doesn't exactly result in the most immersive experience ever. This system from a team at Osaka University is different, relying on three pico projectors all focused on a single column of steam that, as far as we can tell, is dropped down through a slew of multicolored drinking straws. Each projector has a slightly different perspective of the violet hare in question and, as you move about, the fog acts like a parallax barrier, only showing one angle at a time. With a few more projectors and a whole lot more fog the could be even greater. The bunnies, they would be majestic.
