Just thought I'd post this for comments and a question.

Question: I intend to place more objects in the scene. One of the spheres 
needs to reflect a no_image object and its shadow but I don't want the 
shadow showing on the plain surface. Any suggestions would be helpful. I've 
also included a close-up of one sphere's surface just to show the 
highlight - note the specularity.

John

PS Thomas (De Groot) - I noted your question re: Zeger's Greebles and will 
post the modified code just as soon as I can find where and on which machine 
I saved it.

Not tested.
Maybe by making the plain no_reflection no_shadow so that it don't show in the 
reflections but shows directly. Then using another plain just below, only 
visible in the reflections with double_illuminate. Place a second light_source 
under your scene and project_trough a negative light with an inverted copy of 
the "ghost" object to make the shadow appears.
The no_shadow for the top surface permit the bottom one to receive the main 
light and cast shadows. The gap between the two surfaces must be very small 
comparatively to the scene scale.

Add no_shadow to the sphere?

Thanks for the use of your brain cells. I will test it tonight

The plain surface is of course an isosurface. I'll post the texture and iso 
when I have results from Alain's suggestion
