That is a possibility, but if I give you a density of .02, you could guess
that a good gather radius would be around 0.1, but if I give you a density
of 2500, what would your initial guess for gather radius be?  I guess you
could use 1/sqrt(2500)*5 ... and maybe that would be OK... would it be too
confusing, or more clear that what I have now?

Comments?
