A rainbow { }.  The POV-Ray kind.  Seems to be overlooked a lot that one exists
in POV-Ray.  Maybe because it's one of those not-so-easy to control sort of
things.  At least not right away.

Effect of refraction, I'd say, of the horizon.  I think I used too much
transmit in my glass and liquid too though.

Good guess.  A ior 1.01 too.  I used it in the final material { } which had a
texture {texture_map{}} because of not knowing any way to do a material_map.
material_map, as you might know, is not a map made up of material { }
statements.
