Students at Japan's Osaka University are toying with a new tech that creates 3D images projected into mist, you can check it out over here.
Finally, fog can be used for something other than keeping planes grounded. A group of students at Japan's Osaka University have devised a way to use mist as the backdrop for a 3D hologram floating in midair. Using a stream of water vapor and three Pico projectors, the team has been able to render a levitating neon rabbit which can be seen from multiple angles as the viewer moves about the hovering rodent.
The holographic effect is created by taking advantage of the directionality of light dispersed by fog. Each of the three projectors presents an image of the rabbit taken from a different angle—if you stand at one angle, you are presented with the front image reflected through the fog, as you move to the side you'll be presented with the corresponding side of the bunny, etc. The end effect: an adorable Easter hologram.
