Scientist invents invisible coat
Check out this NYT article .
When I first saw this I thought it was a joke. But it seems it's not.
Here a short version of the story:
A scientist, Susumu Tachi, has a raincoat that is partly invisible! Well, really it's not, but that how it looks. The thing is that the scientis has a videocamera-system that can project video onto a special fabric. So what is actually happening is he's recording what's behind the raincoat and projects it to the front-side of it. Neat!
I bet the army can find this useful for camouflage - if they can develop the system further. But this inevention can probably be used for lots of stuff. How about free enterance to the movies and the girls locker room? ;)

And WTF has this to do with security, you might say? Such a cool invention deserves to hit the front page!
