Yeah!
Hey Andy;
I'd entirely forgotten Vonnegut's "chrono-synclastic 
infundibulum"....What a wonderful ,dourly funny man he was.
I'd intended it to mean an enclosed vessel of various compound 
curved surfaces.
The problem is that my hollow bodies tend to be way too, as Mike 
infers,non-ergodic....in that my inconstant working over time 
yields results that don't fit up worth diddle....pf
