The only problem is that it isn't always self similar in proportion. What I
want is a spcific proprtion of the circles that will make it self imilar
proportionally as well.

It's been done...
I got this from Greg M Johnson
news://news.povray.org/3a4e9ea8@news.povray.org. It'll fill any objct with
spheres but it takes some time to parse. But the equal proportions would be
another story...
