:-) Indeed. Somewhere, I've got a book on nothing but spirals.

I guess I see a practical need for some basic capability for vortex 
effects and a few of the more basic spirals. Beyond that, not sure.

Thanks for the additional ideas and especially the spiral code with 
which I play. I've got some of your earlier work on spirals stashed away 
too for when I can really get after the topic.

Heck, I've got a LOT of your general ideas stashed away! I can't keep up 
with you - or jr - truth be told.

On the "bah" comment. One of the things our current spiral capability 
doesn't do well is start and stop exactly where we want it to - in a 
clean way. We have hard starts and stops on numerical limits or by 
fading the effect in or out. The piecemeal assembly of spirals does fill 
a need for clean, limited duration, spirals - admittedly by default! :-)

Thanks for the thought to add the isosurface inside test comment to 
documentation. It's done in the documentation I'm shipping with the yuqk 
fork.

These days, I'm less a fan of massive popularity for POV-Ray than I 
expect you and others are. I'm becoming more and more averse to noise - 
and kids playing on my lawn.
