Gaston Quieto's Monedas Brisas is a quick and pretty on-the-table routine. It's a refreshing break from the usual Matrix/Shadow Coins/Assembly effects. As the name says, the coins are handled in a light and breezy way. I think this is a fantastic addition to any Matrix style routine.
Gaston's effect can be found in the "Talk About Tricks" section of the August 2002 issue of Magic Magazine.
