These are some examples of the Light Globe series. I've left the code sloppy
to give an indication of the method I use to create them. They're all done
in a numbered series that usually starts out with a simple glass sphere,
light, and reflective plane. Then I basically just keep fiddling around
with the variables (IOR, light color, angle and color of plane, sometimes
emission color, etc. etc. etc.) until one finally pops out as interesting.
Then I rename it "9.1", or "9.2", or whatever, and go on to the next one
and repeat the process. When I have enough (I have hundreds at this point),
I can then go back and look at my results, and, if one seems especially
promising, go off on that tangent for a sub-series, "9.2.1", 9.2.2", etc. I
found that if I just kept tweaking the same code, I would often lose an
image that was better than before and not be able to reproduce it. This
works more like prospecting for diamonds in the rough. You dig for a while
in one place and when you find something go on or dig deeper. It's also a
great way to learn how the basic effects of raytracing work.

The included scene files have some colors that may not be in your

sunrise for an outer hollow reflection sphere that I didn't include but
could send if you don't have one.

I forgot to thank you for the files! So, thank you :-)
I often explore POV-Ray byways the same way as you. In particular 
isosurfaces. And I also thus lost quite a few interesting possibilities. But 
worthwhile!
