Your friend didn't explain well the concept.

The phone was insert on the hand, you can "talk to the hand".

If you want image, you just need to put the hand over a glass.

It was a remake so have some stuff from the original and a lot new stuff (history speaking), i have a mix feeling when i saw it.

Sorry about the first image, in a quick serch this is the best image i found of the hand phone of the movie.

The second one is when put it on a glass image thing.


Greetings.
