I will try to figure out how to create the pyramid's "inverse" using my 
code too.

Isn't that "inverse" just an CSG (full pyramid minus "your" pyramid)?

Wow! You are absolutely correct. It probably would have taken me several 
wasted hours to figure that out. Thanks!

Well ... then ... in case you have some hours left over ... build it
from ground up :-)

It turns out, it's not so easy. The "inverse" is supposed to look like this:

I've attached my attempt based on your suggestion and it's not the same 
thing. Anyway, I am busy now and may return later to investigate this 
further.

Can you post the .pov file? Since I need to brush up my pov knowledge I
would like to have something not too complex to examine.

TIA
