There is only 20 spheres in that object.  I only used them where there 
was a hole in the intersection of several cylinders.  I made the spheres 
the same diameter as the cylinders so their locations are not obvious.
For your second question.  I have some books on polyhedra, and I spend 
some quality time in the analytic trigonometry section, of a calculus 
textbook.  I think I mostly just used the Pythagorean theorem though.  I 
am confident that I could make a decent looking geodesic dome with what 
I learned, but I think it would easily take me a whole day to write the 
scene file, so I have been putting it off.  I have been thinking about 
how to do it in a macro.

I made an include file with untextured versions of all of my shapes.  I 
made it for my personal use so it is not very user friendly.  If you are 
interested I will clean it up, and post it.
