Revolve by Nicholas Lawrence
This is the evolution of my popularized folded color change 'Evolve. This gimmick is a utility system that allows you to visually change a folded playing card and hand out for examination immediately.
Routine: 2 cards are folded up into quarters, one Blue and one Red. The cards visually Transpose multiple times and at any time the spectators can examine the cards. They can even switch inside the spectators hands!
