Word on the street says it came from Japan. During a Japanese lecture tour in the 80's, magical genius Michael Weber saw some Japanese youth spinning a card-like object (ticket stub, business card, etc.) on his finger tip.
Weber brought this technology back to the states, and then disseminated it to Europe on another lecture tour a little while later.
It's been published in a couple of spots like:
-Card Finesse by Jon Racherbaumer under the title - "Whirl Flourish", 1992 -- pg. 36-38.
Also in Card College Volume 4 by Roberto Giobbi -- under the title - "Piruette", German Version 1994, English Version 2000 -- pg. 1022.
I love this flourish, and use it on a daily basis!
