Thanks. You've given me an idea...

Reading data for 2000+ particles from file, calculating their next positions, and
writing them back to file is not a fast process. There comes a point where the
time needed for parsing thousands of particles becomes greater than rendering a
few dozen media filled spheres. And unfortunately, this type of smoke sim needs
_really_ high particle counts.
