# Knot

> Taffy pack: a trefoil knot of wide satin ribbon, washed from deep violet through magenta to pale lilac, its edges shifting toward sky blue side on. It tumbles slowly while its ribbons roll along themselves and the colors flow round. A tap loosens the loops, which swell open and cinch back tight. Raymarched in WebGL.
