Synopsis
Three burglars break into an art store in order to steal all of their products, but this safe is no regular one.
Opening the Safe
Imagine the safe has two holes through which you put your hands. Inside those holes you must perform a flourish, a specific set of hand motions, in order to unlock, one by one, the code to the safe. The only backfall of this would be that the viewer wouldn't be able to see what the cardist is performing.
The safe has 4 abstract shaped holes in it. The person unlocking the hole must perform a Display Type of Cut and insert his hands, along with the display, inside of the hole (the viewer will then see that the abstract shaped hole is actually the outline of the display).
Kinect + Scanning your hands for the right flourish to unlock part of the safe. There can also be a small display where the computer shows the name for the move that you must perform (and only an obsessed cardist can know the names to each and every move out there).
You can choose one of these methods or include all three for diversity.
