better and better... I just want something in there
that really highlights and brings out the mechanixcal
spider- I mean gives the metal a chance to shine and
reflect- the shadows are too deep near it and the
contrast a little too stark (IMHO).

This one is shaping up to place at the very least.

But why bother?  I'm not interesting.

Sad :-(.

The image and its amount of details is incredible. OTOH, with such large
number of objects, there is always some details to correct. My list of
things that could possibly be ignored comes here:

-The lamp does not like bright enough. I think the tube should be just
plain white - now it has some shadows.
-The monitor does not cast any light. I think normal CRT in dark room
illuminates quite much, altought the picture in it is quite dark.
-Papers look too much like simple crackle pattern to my pov'er eyes.
-Wood textures are continuous between boards.

You meant something like this?

//--------------

#version unofficial megapov 0.7;

global_settings {
ambient_light 0
radiosity {}
ini_option "+qr"
}

box {-1,1
scale 12
pigment {rgb 1}}

light_source {
<0,0,0>
rgb 0.7}

#declare oggetto=0;  // 0 sphere_sweep, 1 torus

#if (!oggetto)
sphere_sweep {
catmull_rom_spline_sphere_sweep
6,
<1,0,0>,.1
<0,0,1>,.1
<-1,0,0>,.1
<0,0,-1>,.1
<1,0,0>,.1
<0,0,1>,.1
pigment {rgb x+y}
scale 2
translate -y}    //if you close the spline the effect is reduced...

#else

torus {1,0.1
pigment {rgb x+y}
scale 2
translate -y}

#end

camera {location <0,0,-5> look_at 0}

Well, yeah, it should (through the data interface, or whatever it's called
in English...)

Cheers,

Yes, that's very good.  

It indeed looks like a bug to me, there is an easy workaround, just add
another object to the scene like:

plane {y,-100 }

I'm of course in doubt if this also works in your complete scene but in
this small sample it generally seems to work.

Another method to fix it for your scene would be to use Chris Colefax's
spline include file and not the sphere_sweep.
