'Cyber-illusionist' Marco Tempest reveals his tricks
Marco Tempest describes himself as a "cyber-illusionist".
The New Yorker has impressed audiences around the world by mixing traditional magic with technological wizardry.
Some have called his art form "sustained magic", because instead of building up to a climactic moment of revelation when the audience gasps, he strives to keep people in a constant state of amazement.
He describes himself as a practitioner of "open sorcery", because he shares all the software tools necessary to perform his tricks through various portals including his website, with a growing online community of illusionists.
He took time to speak to the BBC while attending the eCircle technology conference in London.
