Not Knot is a guided tour into computer-animated hyperbolic space. It proceeds from the world of knots to their complementary spaces — what’s not a knot. Profound theorems of recent mathematics show that most known complements carry the structure of hyperbolic geometry, a geometry in which the sum of three angles of a triangle always is less than 180 degrees.
