Oh, I suppose a few of those could be worked out here and there by special
request ;)
I posted code for a user-defined function over in the other thread:
http://news.povray.org/povray.newusers/message/%3Cweb.59d2dffc808cf4025cafe28e0%40news.povray.org%3E/#%3Cweb.59d2dffc80

Here's the output for a plain-vanilla 5-arm spiral.
That ought to be a good start, and illustrate why that sphere might be there.
I'll see if I can re-think my approach and rewrite my code to plot the internal
function as a user-defined isosurface, and then it can be experimented with
"natively". Which is what I probably ought to have done initially, but
sometimes I have to do some wheel-reinventing along the way.
