A puzzle, a game, a challenge, a system, a tool ? .. Probably :)

A puzzle to engage your mind into new ways of thinking, from baby steps to giant leaps,

A game to immerse yourself in and enjoy playing, there is no losing. 

A challenge to grow and learn, to train your mind, a challenge to yourself to find different approaches to solutions, a challenge for others to solve a puzzle you created.

A system of puzzle setups, on many base playgrounds (2D, 3D) with varying difficulties, from easy to highly complex.

A tool to see 3 dimensional spatial relations, positions & movements, and thereby understand what may have been outside of your scope.

Maybe a path leading from diversion into clarity, and a quiet focused mind ... who knows ??

One thing it strives to be : FUN.

PS : Tri - na - gon pronunciation :
Tri as in 'Trinity',
na - as in 'nothing' or 'now', it's still an 'a' like in 'father' but shorter,
gon - as in gone.
