Perlin groves

The Black lines (the grooves) is a 20 m wide symmetric groove with the depth between 0 and 1
With zero slopes in the endpoints.

This is pretty cool! I'm wondering if you can to the same thing using the Contour Shader set with some black and white to act as a map and mask.

Another (simpler, faster) implemention.
Multiply the output of the noise function (in this case multiply by 5 )
Subtract the floor (-5, -4,...,0, 1,2,3,4)
This creates 10 ranges 0..1
create a groove in the lower range and a constant 1 in the upper range.
A groove is created by step(1-step) squared and negated  in this case smooth step 0..0.5 is used
