Hi,

i came across this video on BBC yesterday:
<link to video deleted>
Now I wonder how this stuff works in detail?
Is it the carrier wave or the multiplexer signal of the phone?

best regards

personally, I don't believe the video
I seriously doubt that would really work.
More likely some wonderful video editing done

It's got to be dodgy. Those sketch pads would always be going loopy. People (except PF members) would all take them back to the shop.
 
It doesn't look genuine to me. If you notice, the pixels making up the stone between the sketch pads constantly shift. The pixels making up the boundaries of each screen on the pad are also shifting.
