I've been doing some work on creating furballs recently,
and I've come to the conclusion that I wanted to write a
script which places hairs, bends them according to
gravity, but also stays out of planes and spheres (easy
to implement, required for furballs) and uses springs
in order to have no hairs intersect.

Nontheless, I also need springs which pull nodes back
together, as to keep a certain length for the hair.

I don't want to run for animations yet, so I don't need
some magnificient code which I can run through animations,
just some code which can calculate some hundred strands
of hair, grow them from a sphere, and doesn't let them
intersect the sphere, themselves, and a plane underneath.

Any links, or formulaes for springs (both ways: nodes
getting too close, in order to move them apart, and nodes
getting too far off, in order to get them close enough together
to keep the length of the hair)?
