Ok, with this I get the general external shape I
want, but the internal points aren't as mixed up
as I'd like...how do I compute a random point in
the shape such that all parts of the sphere_sweep
stay within the shape?  As it stands, if I change
Z to a random number I get the jumbled-up mess I
want, but it leaves parts of the sphere_sweep on
the outside of the shape.  Solution?
