Princess Leia was apparently indisposed, but Korean researchers are laying claim to the world's first 360-degree color hologram -- a floating Rubik's cube. A 16-company consortium called ETRI, led by LG Display division, has created "tabletop holographic display" that can be viewed from all angles. According to ET News, it's a true hologram and not a "pseudo hologram that make[s] 3D effects through 2D images." In other words, it's not a "Pepper's Ghost" illusion famously used for the Tupac hologram. Since the view changes when you move around it -- as if it were a real object -- it also differs from "floating 3D-movie" type holograms.
