        Thanks: the dome tiling is a macro.
        Red is a difficult color to work with.  Hmm ... maybe
blue ... that always looks good.

        Standard Official Povray 3.1, outputting a 24-bit TGA
containing 16-bit data.  I use the spherical pigment with
a color map (clear to white to clear) to make the rim of the
crater.  That looks way too regular, so under that pigment I
have a bozo pigment. The interaction of the two layers  is
like the photoshop "multiply" mode.  (in other words, the
sphere pigment masks out the bozo into a crater shape)
