Researchers Develop Purely Optical Cloaking

Rambo Tribble writes: Researchers at the University of Rochester have developed a remarkably effective visual cloak using a relatively simple arrangement of optical lenses. The method is unique in that it uses off-the-shelf components and provides cloaking through the visible spectrum. Also, it works in 3-D. As one researcher put it, "This is the first device that we know of that can do three-dimensional, continuously multidirectional cloaking, which works for transmitting rays in the visible spectrum."

It's interesting, but I can't have been the only kid to have noticed my thumb disappearing between two magnifying glasses decades ago.
