Marco Tempest is an illusionist who works with technology, as well as traditional magician's skills like sleight of hand. Although its easier to imagine how you program three iPods to do the things he has them doing in this video, it's still a neat display of skill. After all, most of us don't believe that magicians actually make things vanish, anyway. The fun is that most of us don't know how to do the trick, and we're impressed when the magician makes it work so smoothly. Same thing is true here, just in a slightly different way.
