For anyone who doesn't know, reset is an effect originated by Paul Harris, based on a couple other ideas. It is, at it's core, a double transposition of two four of a kind's. Say for instance, the four aces transpose with the four kings, which are usually isolated in front of the spec', then transpose back so the magician is left once again holding the aces.
I love the Harris original, very nice.
Nate Gibson has some very nice touches on the effect, as does Greg Wilson, Chad Long, David Harkey, and R. Paul Wilson's is very nice visually. Not 'pure' though, although I don't see what difference that makes.
