I have placed 1000 wooden spheres inside this woodbox but it was too much :-)

What in the world were you doing with 1000 wooden spheres? <g>

abacus with hardware memory ?

where lies the secret of the non-intersectional balls? in the 
trace()-function? is there a way for this in v3.1?

partially yes
if you don't know what 'trace' does check description under
http://www.povray.org/working-docs/id000136.html#6_1_4_6

> is there a way for this in v3.1?

yes but you have to know some basic algorithms connected with finding ray's
intersection with objects (i.e. sphere)
iirc you can find some description of it within 'raytracer' part of new
documentation at http://www.povray.org/working-docs/id000107.html#4_2

How 'bout an abacus that does symbolic integration?

As you see from my picture such operation provides to des-integration.

In 3.1 you just keep an array of the positions of the balls (and an
array of their sizes if different). Each time you try to add a sphere at
a random position, you check to ensure that vlength(newposition-
oldposition) is less than the sum of the two radii for each of the
existing spheres.

Hehe, whooo, man... I went into shock that joke was so bad.  ;)
