wow!
I wish I understood how you did this!

I've been learning math for some time. This is a result of raster to
vector conversion. This op isn't complete, because the source image cannot
be reproduced in such a way- some additional info is a must. But, one the
other hand, even this output looks rather attractive. This is a raster,
but it could be converted to vector without much problems. Al nececcary
info is placed onto contours. In short words, one need to have set of
contours (Bezier curves, polylines) and some parameter (you may name it
intensity), which changes along these contours. Savvy? To create such kind
of graphic one may draw curves onto planchette. One may press pen to
planchette with mutable (non-constant- I do not know an appropriate word)
force and set in such way intensity along drawn curve. This is the most
important- fast and convenient method to paint regions without brushes nor
meshes nor vertices... Well, if it is interesting for you, I'll inform
you, when a prog, using this method, is ready. (5-10-15 days perhaeps)

Thanks, I'll inform you, whem my first draft for such kind of painting
will be ready...
