Watch knots tie themselves on a physics-simulated 3D rope

Knots Made Easy shows how to tie knots on a 3D rope that is simulated, not animated: invisible guides pull a few points and physics handles the sag, friction and cinching. Turn the view, pause, slow it down or drag through the steps. Nine knots so far, from the overhand and bowline to the zeppelin bend and daisy chain, each with what it's for and what to watch out for. Free in the browser, no sign-up. Built with React and three.js; the code is on GitHub, but without a license file yet.

    Knot diagrams are hard to follow, and in videos a hand usually hides the crossing that matters. Here the rope ties itself in 3D, so you can stop on the confusing step and turn it around. Nine knots for now, built by one developer in Amsterdam, and 178 stars on GitHub in its first two weeks.
