Friends, the trailer is interesting, neat and led me to throw my $9.99 at the wind.
The Vault is a very cool premise, yet it should stay in the Vault.

The handling of and working with the Gaff is a no go for me. Too much to fiddle with. Also unless you have perfect lighting you will flash the gimmick,... Handling will not allow you to show what was drawn on the pad or your hand until you pocket the marker and get into the gaff. Also, the question of why are you doing such an effect is lost. The angles are week and you have a high chance of getting caught as you get into the Gaff prior to the effect being performed. The creator got my $$ yet, not my praise. I would like to see a few full performances in the real world with real spectators and without creative edits hiding the Magi squirming around to get into the Gaff.
Hold on to your $$ on this one.
