Invisible Cloaks, Translucent Walls

jd writes "The University of Tokyo has developed the illusion of invisibility, under the name of 'Optical Camouflage.' The system is remarkably simple - you have a mix of light-sensitive and light-emitting devices attached to an adapted reflective surface. The devices are hooked to a computer, which simply projects on each side whatever is on the opposite side. The result is more of a translucent look, than real invisibility, but the potential is there. The inventer's next objective is to make walls that are invisible, using the same technology. Project a real outside image onto an interior wall without windows. This almost sounds more frightening than the cloak, since there's no reason why the sensors would have to be placed outside. Imagine a world where PHBs can turn their office wall into a window onto any cube. Zero privacy. The technology is great, but the potential for abuse is definitely there." Update: 06/15 00:20 GMT by T : You may remember we mentioned this project when it was cloak-only.

It permits them to see things located in another place, live, or they can store the collected images as a motion picture of sorts and refer back to it later.

    It might confuse the hell out of sharks, too. Especially if the makers can keep it from shorting out, and if it can project menacing images to deter the shark. Maybe it might be better to just give chemical repellents to the people in this predicament.

    Halloween parties could be really freaky, especially if the shimmering effects make the kids laugh.

    But, we would have problems if people in these digs (with audio effects) were running around shimmering and growling in Leisure World. Might kick some tickers into overdrive.
