Thank you guys very much for the suggestions. I'm constantly amazed and humbled
by everyone's abilities. This may be a good time to learn some new things that
I've never tried. The isosurface features, as suggested by Anthony D Baye and Le
Forgeron, sound promising.

Kenneth, I'm going to experiment with your code a little. I'm wondering if
increasing the resolution a lot and using a gradient defined by a non-linear
function instead of an abrupt pigment transition could create the curved edges
of the "pineapple" bumps. And, unioning in a plain sphere scaled just right
could cover up those extra indentations handily. Thanks so much for your help!

Regards,
Dave Blandston
