As far as I can tell, this approach ought to work great with any arbitrary set
of sizeless points.

As Dave points out, once you start to add some volume, things get offset a bit.

If all of the points on the ballerina's surface were used to create a positional
average, it ought to work just as well, so maybe a trace() approach would be
simplest.

I'm sure there might be a way to do it where the point-center is found, and then
the blob sphere center point vectors are weighted according to the radii.
Probably hard to parse and understand that, but I think a diagram would show
what I mean...
