Yes, the way it is simulated causes that vibration. I don't like it either;
maybe a finer simulation will help reducing the magnitude of the vibration
and make it less evident.

One of the advantages of my algorithm is that it can be parallelized, that
is, I can use several machines to code several frames independently, because
the coordinates of the particles are given by my C program. Can it be done
similarly with SDL or POVRay-patch?
Thanks for the suggestions,
Fernando.
