Different approach...maybe. Totally the concept, it is about... I draw the
standard concentric circles(internal wood pattern) there, but I change the input
coordinate (x, y, z) to (x/factor(..), y/factor(..), z), than it distortion the
original space on x-y plane direction.

The knot is the same. I distortion the pattern shape in a narrow range, (vs r
theta and z)
