Not Knot (Parts 1 and 2)

Not Knot is a good thinking trigger.

I enjoyed topology when I studied it and I still remember trying to imagine multi-dimensional spaces and then having to draw them on a highly inadequate 2 dimensional piece of paper.

According to the Not Knot blurb on YouTube:

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.

Here's Part 1:

Now for Part 2:
