It's Not Quite Holograms, But Getting There: the L3D Cube
A new product from a Brooklyn company that specializes in physical 3D visualizations is the Pong of holograms
Consumer applications of holograms are still a long way off. In fact, even the Tupac hologram at Coachella 2012 wasn't a true hologram. Still, clever makers are coming up with workarounds, and one team in Brooklyn may have brought the world of true, 3D images to the Pong level. You be the judge.
The Looking Glass Factory has a Kickstarter campaign up (that's already at well over twice its goal) for the L3D Cube.
It's an 8 x 8 x 8 cube (or a 16 x 16 x 16) made up of multicolor, bright LEDs. They are all driven by Arduino and on a thin enough mounting that enables the eye to effectively see through the mountain. Your brain fills in the gaps as you look. The various lights are able to flash on and off in such a way that they create 3D shapes.
