Do you mean the colors on the surface ? The surface consists of individual triangles
(14492) and was generated by a molecular graphics program GRASP. The colors on the
surface outline the contributions of certain types of atoms to the surface. i.e.
white surface area = CB atoms etc. ( This is why it looks a bit odd. It is
delibrately not smoothed ).  In the animation the filter value of
the colors of the surface was varied from 0 to 1 and back while at the same time
white was added
to the color up to 80 % to make the surface really transparent in the middle of the
animation.

'Loopable' meaning  a full rotation of the sky so that one would not see the
begining/end of the animation ? I tried this but the sky is just way to fast for 45
frames. I tried a still sky with clouds forming and disappearing but I had trouble
with this too because I did not want to 'undo' exactly what was done. Anyhow I agree
the sky is not too good. I have not used 'extra' things in povray alot
before - only molecules and surfaces but rarely planes ( floor ) let alone sky !

Thanks for the comments. I really appreciate this.
