Sortable is a visual approach to triump-h, perfect for walkaround. The spectators can see the cards being mashed face-up into face-down.

A card is selected, and optionally signed. Then the deck is shuffled by both the magician AND the spectator. Next, the deck is mashed together face up into face down. It's clearly a mess.

Finally, with no suspicious moves, all the cards magically turn face up... except for the selected card. 

No Culling
No Rough and Smooth 
End Completely Clean

Simply by squaring up the cards, you can create order from chaos.
