The size of the pic is too small. My desktop has 1152x864 pixels!
O.k., this was meant as asking for posting the source code... ;-)
Cheers,

Hello Pete,
I like this picture very much: it's a nice combination of geometry, art
and raytracing. As a mathematician I'm interested in polyhedra (as one
can see on my website), but being a novice in povray I'm interested in
the source of your picture or, if you prefer not to distribute it, tell
us more about the construction of the object based on the dodecahedron.
I'm sure that I'm not the only interested person.
Friendly greetings!

Cool and very nice. Very sci-fi-ish.
Any chance of seeing the code, please?
I'm interested in seeing how you did the grid.

Umm, well ... the construction of this dodecahedron is
not mathematically "pure". Two angles are used to rotate
copies of a pentagonal "face" object. One angle is 72
degrees (easy, as it is a known integer value, being 1/5th
of 360), the other was ... um ... derived by trial and
error.
Code is posted as a zip on povray.binaries.scene-files.
2 warnings: (1) it uses v3.5 features (2) It needs
nine bitmaps to build the background hallway pigment.
I've not included them because they are huge and are
not that important. Just use any nine pics you have
lying around.
Pete

didn't think of that. That was a cool game. I never
lasted more than 12 seconds .. but I liked the fact
that it was a true 3d game, making full use of
all three dimensions.

Thank you for putting the code available. I'll certainly have a look at
the part about the "dodecahedron". The object is very nice and your
method to obtain the other angle by trial and error gave a good result.
I'm sure one can find the value in a pure mathematical way and after
examining your code I'll send it. Unfortunately I can't do it to your
personal e-mail address because I can't get this from your messages.

I really like this one and your previous tech style image!
One idea: Next time try to put the object of interest somewhere else than in
the center of the image. It will look like you've put even more thought into
the design... :)

You won't believe this, but I usually put things in one of
the locations specified by the "rule of thirds". It's just that
for these two renders, I liked the look of the "center of interest"
right in the center.
