While experimenting a little bit more with the shape that was used
in my last posting "Two spheres" I rendered this image.

I was surprised by the strange patterns created by the "endless"
reflections.

I used a little bit too much light in the scene and because of this the
image "bleached" a bit.

So instead of doing the 15h rendering again, I just cheated and did
a gamma correction. =|

I see that also this image could use some softening of the shadow,
but I have not had time yet to try this out.

A question:

Does anyone know if there is any way to make the light reflecting
from surfaces to fade as it is travelling to the next surface?

(I think that if this is possible, it could also help preventing the
image
from "bleaching".)

Try MegaPov's reflection_falloff. Intriguing image!

This is a nice render anyway.
The "bleaching" as you called it is most likely the result of pigment color
contribution to the reflection, if I understand which part you are referring too.
'diffuse' is what controls that so if you use a low diffuse value then it won't
saturate the reflections with the objects own colors.
'reflection_falloff' controls angle dependant reflection in a way that's
somewhat like light fading except it varies the reflection from minimum to
maximum angles, so that probably wouldn't help much for this.

I have not installed MegaPov yet.
(But maybe I will some day.)

Thank you. 

(I did not have any idea of how the reflections 
would turn out before I rendered it. And I don't 
really understand all the reflections yet.)

I have now tried the diffuse keyword, as you suggested above,
and then the "bleaching" disappeared.

Thank you!
