Be aware that with my approach the contour lines itself are not changed during
the iteration. So if you have thick lines or lines that are to close together
you will yield steps as well. With my approach you can run one or two additional
iterations without the seed to smooth this issue.

Being mistaken with one of the masters I take as a compliment, but I'm far away
from Sam's mastery. May be I'm not a rookie but I'm still an apprentice.

Best regards,
Michael
