It's called "Trangleball." Which is like "Triangle Ball" without the "i" - because, as the developer explains, "there's no I in TEAM."

Official Trangleball equipment includes a 14-inch high pyramid and 6 "Mini Trangleballs" each about the size of a softball. There are rules for Trangle Soccer, Trangle Baseball, Trangle Basketball, Trangle Stoopball, 1-on-1, 2-on-2, and the traditional 3-on-3 versions of Trangleball. Yes, I know, it sounds wacky. So many games from such a simple device - a pyramid in the middle of a circle. And yet, as so well-illustrated, Trangleball is a genuine invitation to active, creative, athletic play.

The inventor explains that the the real "sport" is the 3-on-3 version, which he calls a "3-dimensional handball" game. There are two teams, with a member of each team in a different sector. When a ball is served, by throwing against the Trangle, the opponent can catch the ball and rebound it onto the Trangle, or pass it to one of his teammates in another sector. You can read an article about it here.

Trangleball is the very stuff of fun - a small innovation that lends itself to the creation of apparently endless possibilities for active, physical engagement. It looks good enough to be a candidate for the development of a whole series of professional sports, and open and flexible enough to be played in backyard, street and playground. The site isn't very fancy. The pictures not really professional. But the spirit that is conveyed is Olympian.

Kudos to inventor Mark Miller for his courage and playfulness, and for extending to us all a new opportunity to engage body, mind and spirit. Questions? Wanna learn how to make your own? Email Mark.
