Japanese professor Susumu Tachi at the Kelo University claims that he and his research team have finally developed a system that can make you "invisible."

Professor Tachi has spent the last years developing ‘invisibility goggles and invisibility cloaks’. With this invention he wanted to create a vision of invisibility, for example, to make a room that has no outside windows appear to have a view to the outside, and then the wall would appear to be invisible.

The 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.

The key development of the cloak was the development of a new material called retro-reflectum. This material allows you to see a three-dimensional image.

There are many ways to use the cloak, from espionage and military purposes to helping pilots see through the floor of the cockpit to the runway below. Also surgeons might use it during operations to avoid having their fingers or surgical tools block their view.
