I was actually afraid that the method was the same than for iCurveball. It is not. It is really
open. The spectator see the screen while you scroll it and also when you stop on his command. It is
really fair and direct.
You have to hold the phone in the strange manner that you can see in the
trailer but from my point of view, it is ok.
Nefesh propose alternative techniques and
presentations that from my point of view are less interesting, but can interest some mentalists.
The main anchor technic really worth it. Great approach!
