    Yes, that has been gnawing at me a bit.I'll probably experiment a little
with superellipsoids there, but I can visualize that something unwanted will

But I have an idea now that I think of this, that might do the trick.

Looks pretty good, but there is no need to make it wrap aroung the pole.  See below.
