Well, this is shocking and impressive at the same time. Apparently a group in Japan could make a way to transfer vi 40MHz data between two objects, via the human body.
In the demonstration, you touch a metal heart, and a video show up in some kind of goggles that keeps touching your face with some kind of metal. A little strange for my taste, but way cool! You can follow this subject in the Brazillian terra, here.
Jhonny Mnemonic anyone?
