I really like this one, particularly the scene layout.
To give more randomness to the start (and therefore the end positions), perhaps you
could add
a random velocity to each mass when they are created. I would do it like this:

#include "rand.inc"
#declare TT=seed(7);
#declare Variation=0.2;

mass {
        <0, 0, 0>,
        <RRand(-Variation,Variation,TT),
        RRand(-Variation,Variation,TT),
        RRand(-Variation,Variation,TT)>, // Maybe leave vertical velocity at zero?
        0.1
        density 600
}

Also, you could try changing the error_bound to something like 0.8 or 1 (is it
currently at
0.1?), which may help with the radiosity blotches you are getting around the spheres
(at the
expence of accuracy though).

All the best,
