Professor Susumu Tachi of Tokyo University has made a coat that you can see through just like Harry Potter's invisibility cloak.
The picture on the coat is made by a viewfinder which puts together the moving images which are behind the wearer.
The Japanese scientist hopes one day he'll be able to make you completely see-through.
This should help people like surgeons who would like to be able to see through their hands when they are operating.
But we reckon it would be best for sneaking round school corridors when you're meant to be in your house dorm!
