He's a very famous magician with a "cool" and "dark" persona that the young people like. Some of his tricks are standard but then he has others that leave wanna-be magicians like me scratching their heads.
this video is a more modern and freaky version of the saw the lady in half trick. I couldn't tell you exactly how he does it, but remember that there are no wasted movements in a magician's act - it is all carefully planned to draw your eyes where he wants them
