Tri-Thology is a new and innovative flow/skill toy consisting of a looped string with three slideable rotatable handles. As you might imagine, and as you will see as more and more videos of Tri-Thology are posted, Tri-Thology is closely related to Astrojax. In fact, a number of moves are the same, and it appears that there is a direct mapping between a whole host of Tri-Thology moves and Astrojax moves. Tri-Thology can also be spun just like Meteor and Poi. The toy has an endless realm of possibility. Simply put it is like playing with Geometry.
