The concept behind Clone sounds freakily supernatural: the gadget promises to create an exact duplication of a signature. It was good enough to make FISM judges disqualify J.C. Rodarte because he appeared to be cheating and it recently scored a win for Adam Wilber on Penn & Teller: Fool Us. It’s now available for sale, but lots of magicians still have questions about what the heck is going on with Clone.

If you are one of those quizzical folks, then check out this Q&A by Christophe Jelinski of Magic Mind with Clone’s creator. It’s a 25-minute video that covers the development of the tool into a commercial product, its distinctions from Rodarte’s limited-run Miracle Maker, and where he got the idea for the whole thing.

Now that you know more about Clone and Rodarte, here he is giving another demonstration of how it can be used in a wild riff on Three-card Monte.

J.C. Rodarte was disqualified from the FISM competition two decades ago because the judges thought he was using a stooge. Now, he’s gone public with exactly how he pulled off a trick so good it seemed like he was cheating, and the tool is impressive enough to net a win on Penn & Teller: Fool Us.

It’s a tool of Rodarte’s own creation that he’s now planning to sell as Clone. If the promo video (and the many shocked viewers) are to be believed, Clone can perfectly duplicate any signature onto a wide range of objects, from dollar bills to playing cards. 

Rodarte’s not the only one to boggle even the pros with his invention. Here’s Adam Wilber using it in his winning trick on the season 4 finale of Fool Us:

For any of you season 5 hopefuls, be warned: the skeptical duo are probably onto the Clone approach now.

Clone is available for pre-order from Ellusionist with a price tag of $147. Shipments are expected to start around December 6.
