Just an experiment.

I borrowed an idea from Norbert Kern:
http://news.povray.org/povray.binaries.images/28465/

- and a texture from Tek:
http://news.povray.org/povray.binaries.scene-files/31618/

Instead of using a slope mapped texture for the whole shape,
I added a different slope mapped texture to every triangle
in the mesh2 that was used for the shape. (The direction
from the location of the camera to each triangle was used as
the slope direction for each triangle.)

I used radiosity and HDRI in MLPOV to render the image.
(No light sources was used, so the texture does not show
much of its glitter and noisy normals.)

The image was scaled down and had both its brightness and
contrast increased by 10% prior to posting.

Woah that looks nice. You should try it with light sources :) ...In fact I might
have to try it myself.

Okay here's my version, inspired by Tor's. It's the same principal but the
colours are based on paint I've seen on a lot of TVRs.

It has a dome of light sources, like I've been using for my other HDR renders,
so the metallic shading and glitter effects are in effect. But I'm lazy so mine
is just using the camera's direction for the slope_map, not the true vector from
the camera to every point. The error isn't obvious but it's there if you know
what to look for.

(P.S. etiquette question: should I have started a new thread with this message?)

Thank you.

I'm experimenting with light sources right now
but it is difficult to get it all right.

I downloaded ThumbsPlus v5 (Great program !) and have played
around with its morphological gradient filter (and other features).

Here are some results of my playing:
