The ball is effectively an inflated skin, the only significant mass is 
on the shell with the central mass just being a place holder to attach 
the "air pressure" connections. The point masses are an approximation of 
the surface area neighbourhood of the point.

An asymetric weighting of the ball might be fun to try, I'll give it a 
go ...

Bye for now,
