First try at colored crystal using color on the texture and interior 
media (just a test: no aa).

   Thanks!

   The variety on the world of natural crystals is awesome, so, yes... it
could well be a source for a COTW page on my site. Thanks for the idea!

   TBH, mostly due to sticking to what I know and can type from memory.
But I also seem to remember having done a few tests and finding sslt was
slower for some simple effects like this one... but maybe I'm wrong.

Excellent, shall keep my eyes open for it :)

Honestly, I don't use either of them often enough to do anything quickly, or to
know which works best in any given scenario... was just curious!

Incredible. :)  Nice work.

Wow, that is an interesting turn! Thanks from my side, too! I will
experiment with different backgrounds.
