Check out the online video, it looks really amazing !!!
I can only say WOW...
A card is freely chosen by a spectator, signed, and then returned to the deck. The cards are fanned out on the table and three cards are chosen by the magician and shown to the spectator in a fan. The magician then asks if any of the three are the chosen card, and the spectators answer, no. One card is now put sideways at a 90-degree angle and then slowly pushed right thru the other cards and it visibly changes to the chosen signed card. Super Clean.
The film Clip shows the last part of the effect.
