Chris "Jesus" Ferguson. It's very impressive.
Ricky Jay (an astounding card-trick master) also does some pretty cool ones. He can throw a card from 15 feet and make it stick into the outside of a watermelon. He also does one where he throws a card and makes it boomerang back to him, and while it's in flight, he'll pick up a pair of scissors with his throwing hand and cut the card in half on its way back past him.
Pretty crazy. I also found
this article captivating. If you don't have time to read the whole thing, start at "I'm always saying there's no correlation between gambling and magic." What follows is a description of a trick that must be truly awesome to see in person. My mom took my dad to one of his shows as a birthday present, and my dad got picked to be the volunteer from the audience who sat right next to Ricky as he did several tricks. My dad says they looked just as magical 24" under his nose as from 20 feet away. None of his techniques were perceptible, even sitting at his right hand.
