Here is an illusion you don't have to be David Blayne, David Copperfield, or any other magician named David (for that matter) to be able to afford to do.

As for how to create this optical illusion yourself, you are on your own.  I'm no illusionist - though I do think I could saw a woman in half if she were a mannequin.
