Wow that was a cool link, thanks! That is a pretty impressive painting 
technique.

I have tried to print photos taken with a fisheye on glass spheres but 
the b/w liquid emulsion (liquid light tm) I was using slid off the glass. 
If I still had a darkroom I would try again but this time I would etch 
and perhaps starch the glass first. 

I also encountered a problem w/ the depth of field of the enlarger. Of 
course I had a piece of crap enlarger, perhaps using a smaller appeture 
on the enlarger and/or smaller sphere would have taken care of the depth 
of field problem. 

I am sure this technique would work if you wanted to print an anaglyph on 
a sphere.
