This isn't something new. That's one of the features of my nokia 3110 classic.
Other features of them are the 3rd eye application, that you can actually see ghosts. InterGalaxy chat is also a cool feature since I'm able chat with aliens some 2 billion light years from earth.

Intawn pud aneh oi. Please look up the word "x-ray" and see how that type of ray penetrate through objects.
