4About it
A torus knot is a knot that winds around the surface of a donut shape, called a torus. It goes around the hole a few times one way while it loops through it a few times the other way. The simplest is the trefoil, which winds 2 and 3 times; it is the simplest true knot, one that can never be untied without cutting it.
Tap it and the knot is pulled loose, its loops stretching and swirling; then it is let go and springs back past its rest shape and wobbles to a stop, like a spring. Choose winding counts (2, 3), (2, 5), (3, 4), (3, 5) or (2, 7) in the Splash tab: the pair counts turns around the torus's two directions. Colors changes its palette and Glow its brightness.
