Hello POVers!
I tried some ideas for the SCC4. Here is a attempt (not my entry, so I can
share it now) with the following (verbose) code:
plane
{
z,9
pigment
{
checker x+y z
}
finish{ambient 1.5}
}
cylinder
{
z,8*z, .5
pigment {rgbt 1}
normal{spiral2 5}
interior {ior 1.3 dispersion 2 dispersion_samples 99}
}
torus{.7,.2 pigment{rgb 0} scale y/9 rotate 90*x translate z}
Regards

I like this it is pretty and colourful
By removing the line feeds and extra spaces I got the size down to 244
charters, and by changing the torus to a disc, down to 200 charters. If you
I see the attraction of the contest :-)
disc {
0,z,2,0.4
pigment{rgb 0}
translate z
}

Here is another configuration:
disc {
z*99,z,40
pigment {hexagon rotate 90*x}
finish{ambient 2}
}
sphere
{
z,.45
pigment{rgbt 1}
normal{wood scale .24}
interior {ior 2 dispersion 2 dispersion_samples 200}
}

I think the one you didn't enter (mainly and especially the first one) puts
the ones I DID enter to shame. Very pretty.

You can reduce it still further like this:
disc{0,z,2,.4 translate z}// you save another 14 characters
No need for the pigment as the default IS rgb 0!

Thanks you all for encouragement. This principle of having a pigmented
background with a highly refractive glass with a patterned normal can be
endlessly derived and I found it quite efficient in colors and shape wrt
amount of code!
Here is another variation I did not choose as an entry (but I hesitated
....):
plane
{
z,9
pigment
{
hexagon rotate 90*x
}
finish{ambient 3}
}
union
{
torus
{
.25,.25
pigment {rgbt 1}
normal {quilted scale .1}
interior {ior 5 dispersion 5 dispersion_samples 99}
}
torus{.7,.2 scale y/9}
rotate 90*x
translate z
}

Earlier on I was thinking in terms of a reflective tube like a kalidascope,
but alas I somehow didn't even do that. Now you have me wondering why I
didn't.
