This one? http://www.markmark.net/clouds/ I can't find any reference in the site or the papers there to simulating airflow.

The particle method is good, and quick. We still need better smoke/contrails - the hack using ballistic objects is not very good (my code - I can criticize it). The problem is the way transparency is handled by plib, and I can't see a way round it. Still, no one else complains ...
