I like this. AND the previous render with more bubbles. Beautiful.

BTW, I did not realize that an object with ior could have inclusions (other
objects) with *different* ior's-- I thought such constructs would be an example
of 'variable' ior within an object, which cannot be accomplished in POV-ray,
AFAIU. I had a mistaken notion that the camera ray would 'see' the outer object
surface first, which would then set the ior for the entire union-ed CSG. (Kind
of like the way media operates.) But that's not the case! :-) So I've been
experimenting with this multiple-ior CSG trick, which can produce some visually
interesting results. Thanks for the idea.
