Another version:
As an attempt to remove to much regularity, I skewed the bottom path by half a wavelength. But this make some intermediate paths be straight lines. Not too visible on the full-scale image.
- Straight paths along the top and bottom edges
- Path-waves to make them wavy
- Path-inbetweener to generate the 101 intermediate paths
- Path rendered on four layers (1,2,3,4 pixels)
