The basic idea of the effect has been around for a long time (that was actually mentioned in the
explanation), but it was a great reminder of how these off the beaten path concepts can be reworked.
I feel like the presentation was more of a very basic demo than a full working of what the method is
capable of producing. For a practiced card handler this is a great piece of information that can be
used to fool seasoned pros. (Maybe not with the effect as performed, but with a little thought...)
