Thank you, I'm still thinking about the pattern function, but cannot see a gain
with them. First because my experience with them is very limited and second
because my contour lines range from black to white, so using the maximum would
only reverse the problem.

The second idea, starting with a larger area and decreasing it during the
animation, sounds promising. I will give it a try tonight. I used the 15x15
because it the largest grid which is quadratic and centered and fits into 256
map entries.

Best regards,
Michael
