I rendered something new just to make sure that I use all available cpu
cycles while I was doing other things.

Nice and soft.
The colours on the bubbles should have sharper edges I think.

How can I do that? Maybe I shouldn't use iridiscence and do the texturing
"by hand"? Or can I do this by changing the current thickness and
turbulence?

That would be a good thing to be able to do with irid{}. As it is now it
looks like the way it is created makes for something like a bozo pattern
with a triangle wave in the pattern.
Checking it in the source code here I found it in lighting.cpp. I can't make
head nor tails of the actual way it gets created but I changed it a little
to see what would happen. I got narrower bands of color is all. Does so
already if you raise either thickness or turbulence, which appears to almost
scale it inversely as the values are raised. But I think I know a
possibility to set it up to be sharper boundaries so I'm going to try that
next. I don't know this C++ programming at all, or enough to confidently
modify it right.
Anyway, the turbulence counterparts, lambda and omega, are set in the source
and unchangeable within your pov script. Only thing you can change is
irid_wavelength; to shift the color spectrum, I guess you could call it.

Not bad at all, I like the colors. One minor nitpicky thing, though: When
two bubbles are joined together like that, the intersection does not follow
the curve of the larger bubble, but is instead a flat surface.

As matter of fact, it's already a flat surface but almost impossible to see
that.
BTW I'm rerendering the scene with some added things.

I'm back. No such luck. Anything I tried (hacked) was a failure. I could
only get different falloff rates and color shifts. All turned out like a
triangle waveform pattern for each color. I stopped myself before adding new
color stuff since I'd have only gotten lost in it if I had tried it. Was the
wrong direction to go anyhow I believe.

Maybe something to look into for the next POV-Ray release?
I guess if I want better iridiscence *now*, I'll have to texture the bubble
"manually".
