Oh - Sorry about this confusion.

I should have mentioned that it is the red and 
blue tube like net that are made with two iso-surfaces.
(One blue iso and one red iso.)

The glass-"sphere" thing is made with CSG, but 
as David pointed out, it isn't easy to see it's 
real outer or inner contours.

If you have a look at the leftmost shape in the 
last image within my post "Inside It" (17. Jan. 
2001 to this NG):

then you'll see one half of the shape I used in
this "Outside it" scene.
