Well, i thought the slope pattern might be involved.  In this case it 
would only work well for a distant light source, otherwise you would 
need the aoi pattern instead.

Looking closer at the image reveals that there are indeeed problems, 
strong scattering occurs at places where it should not occur.

I have two other things in mind:

1) you use saved radiosity data from a different but related scene 
setup.  This is far fetched of course but it might be an intersting idea 
for such effects

2) you use trace() to place blob components on the surface and use the 
blob with the object pattern (not sure how you could achieve the smooth 
transit with this method though)
