We've seen apps in the past that have done some neat tricks, like creating optical illusions or three-dimensional holograms. But that wasn't enough for magician Marco Tempest. He actually wanted to incorporate an iPod Touch into his act — three of 'em, in fact. And the results — as you can see in the video above — are astonishing.
Done with mirrors? Nope. Tempest actually developed a custom app called MultiVid to aid in the illusion. It's described as "a multi-screen synchronization playback solution for iPhone and iPodTouch…designed for economic playback of video content in multi-screen synchronization applications for theatrical performances and for visual artists." Basically, each iTouch is pre-loaded with a collection of video clips; triggering playback on one starts synchronized playback on all. And Tempest isn't just giving away the secret of his magic trick — he's giving away the app as well!
