Find the center!

O.k. here is the problem:

There are a bunch of points in 3-space and they are supposed to be 
scattered around the surface of a sphere. You want to find the
center of the sphere and the radius.

NB: The data are noisy (about 2% of the radius) and only cover a patch 
on the sphere.

I think I have a reasonable solution, but maybe someone knows of some 
real elegant method?

Thanks,
