So, this is representative of what I think he wants - minus the closed loops
inside the "knot".
That can probably be fixed with a function pigment color map, or just difference
the object or a surrogate from the plane.


plane {y, 0
 texture {
  pigment {wood
   warp {
    black_hole <0.5, 0, 0>, 10
    falloff 7
    strength -5.0
            }
   color_map {
    [0.0 Blue]
    [0.2 Blue]
    [0.2 rgbt 1]
    [1.0 rgbt 1]
   }
  }
 }

  texture {
  pigment {wood rotate y*90
   warp {
    black_hole <0, 0, 0.5>, 10
    falloff 7
    strength -5.0
            }
   color_map {
    [0.0 Red]
    [0.2 Red]
    [0.2 rgbt 1]
    [1.0 rgbt 1]
   }
  }
 }

}
