Knots take a nearly 1-dimensional object and generate a 3d structure that is both durable and potentially useful, sometimes bordering on life-changing. That's super cool. I think a lot of us also have a bit of a primitivist streak, and knots are a low technology that can replace a lot of higher tech and still get a lot done (compare to HN's enduring fascination with Forth).
