Used a modified image from Daniel Mathews posting Grime example of Aug.
31st.

I had to take it into PSP and apply Gaussian blur of 3 to it so that the
contours of the image would be smoothed, otherwise they were too sharp.  I
had done that before but forgot to mention it.
This one uses a slope dependant texture on a isosurface in POV-Ray 3.5 Beta
1.  Also has a 'facets size' normal (good for spheres and similar shapes) in
the uncorroded portions but too small to see.
This is one of many variations and the bright green, seemingly glowing,
parts look somewhat peculiar.  This was also animated to go from shiny and
new to a aged and oxidized appearance as it rotates.
Just playing, but it was asked that images from v3.5 be posted, so....
