A scientist at Tokyo University has developed a coat which makes those who wear it appear invisible.
Professor Susumu Tachi told the BBC’s East Asia Today that the coat was made with a special type of “retro-reflective” material, which acts as a photographic screen.
The image from the camera is then projected onto the coat, so that the wearer appears virtually transparent when seen through a viewfinder.
Beforehand “it looks like a grey coat,” Mr Tachi said. “But when we project the image onto it we can see a very clear picture of what is projected.”
