The Japanese inventor behind that invisibility cloak everyone was chattering about last year says that his next project is to build “invisible walls” so that a room without windows could appear to have a view to the outside. Or you could just install windows. Your choice.

OK I don't know anything about this & I can't even be bothered to do the research but to me that 2nd pic just looks like some1 standing in front of a projection screen & the pic is being projected onto him. Hmm?
If not & this cloaking thing is real then
how does it work!?

Professor Tachi's cloak works by projecting an image onto itself of what is behind the wearer.
A computer generates the image that is projected, so the viewer effectively sees "through" the cloak.
Invisibility material may allow pilots to see through the floor of their planes
The key development of the cloak, however, was the development of a new material called retro-reflectum.
"This material allows you to see a three-dimensional image," Professor Tachi said.
"This material is the key to our technology."
There are many potential uses of the cloak, ranging from espionage and military purposes to helping pilots see through the floor of the cockpit to the runway below.
However there are massive questions of potential misuse too, particularly surrounding the huge crime implications.
It would become incredibly difficult to spot a thief, for example, if the items they were taking were simply disappearing under the cloak.
Professor Tachi said that he had first had the idea of developing something to make objects invisible in 1977.
But he said it was "hard to make it into reality," as the image looked flat and unrealistic.
"It didn't work at all when we just projected the image onto a normal screen," he added.
"We tried hard, but it took a while before we came up with this retro-reflective material."

Thank axxxr for that reply.
WOW this really is interesting stuff. I'd love to see someone wearing it (I know the idea is that u don't though
) but it'd be like Predator!
