I've never come across them before, but there are a lot of videos of Christian Chelman on youtube now.

This one's in French, but I'm sure you'll get the gist of it.

Amazing...

This is the Curator's description of it from...another forum.

"Ok, the routine is in French but easy to understand.
A deck is borrowed and totally shuffled by the spectator and the magician.
The cards are spread during one or two seconds, face up. The magician asks if the spectator did memorized the 52 card sequence. He ask for a number between 1 and 52. In this case, the spectator calls number 24 and thinks that the 9 of Spades is the 24th card. The magician says no! He believes that the 24th card is the queen of hearts. Then, he finds the location of the three other queens.
At the end, the spectator places the queens back in the deck. The magician remembers him that the first number called was 24. At that point, the cards have been "rearranged", and the 9 of Spades is at the 24th position.
The routine is strictly impromptu.
That's how a bizarrist does cardmagic."
