It started out as a glass globe with a miniature thunderstorm inside, but I
had problems with the media and so went for this instead. The spheres inside
were generated by one of my first macros. Anyone know how to get media to
work inside a csg'd sphere? All I got was black, and when I increased
max_trace_level the media just disappeared.

The rotating balls would make a neat web-page gizmoid.
did you remember to use the "hollow" keyword in the right places?

I think I tried hollow- should I have the outer sphere hollow as well as the
csg one?

Without seeing some code I can't be sure. But, it occurs to me if you have two
spheres - a small one differenced from a large one -- and have defined the media
for the small one, you won't see any media. You've essentially told POV "I don't
want this sphere, just its surface from the larger one." To do what you want you
would need to define a third slightly smaller sphere with a transparent surface
and move the interior statement to it. Make sure this third sphere is hollow.
And of course, make sure you're not getting any warnings about the
camera being in a non-hollow object.
