. Tangle® is a series of 90-degree curves, connected and able to pivot at each joint. It has no beginning and no end--just continuous motion. Experientially, a Tangle is much more. The motion it creates is hypnotic. Adults and children of all ages can't seem to put the toy down. Warning: This toy can unleash extreme levels of creativity! From the first interaction with a Tangle, subjects compulsively search for patterns and abstractions to express themselves.
