Scientist in Japan Creates the First Invisibility Cloak

A professor in Japan alleges that he has invented an "invisibility" cloak, with plans to develop "invisible walls" as well.

Susumu Tachi was in San Francisco earlier this month at an exhibition where he showed off his new invention. Supposedly, it's made up of thousands of tiny beads made of a new material called retro-reflectum.

Sounds like something out of Harry Potter, doesn't it? Ridiculous!

Retro-reflectum is a technology that basically allows the thousands of tiny beads to project an image onto itself. You can check all the details here. It projects the image of what is behind the person wearing the cloak. "This material allows you to see a three-dimensional image," said Prof. Tachi.
