So far you are the most correct; no_shadow on the sphere, and the backwards
shadow is indeed a texture layered on the plane. However, it isn't leopard, it
is an object pattern texture (from the sphere in fact), blurred according to Ron
Parker's post earlier, "The final word on blurred reflections" which works just
a well on pigments.

I thought this might be a good way for someone to fake soft shadows in Rune's
fast grass macro. It would take more work than I've put in here, but it does
offer possibilities.
