Have you ever wondered what a knot looks like rotated 40' or maybe 90'? Or maybe you want to see what a Bowline knot or Constrictor knot looks like from the back? Use your finger to spin the knot and see how it looks from any angle in 3D. Choose from 121 different knots and see how they're tied in incredible detail. Watch the knot draw itself or use your finger to tie and untie the knot.
Its easy to see where the virtual rope goes in and out and around. (Something about a rabbit and a hole and a tree right?)
