That's a nicely written, approachable article for those of us who have forgotten much of our university studies. I should add that anyone wanting to put fluid dynamics into their program might also wish to google about for papers on opengl and GPUs performing the calculations. To see a game that makes an interesting use of fluid dynamics you could look at pop-pop from Ambrosia Software. Completely ungamerelated, but the background of the playing field appears to be a fluid simulation reacting to the play elements. It is beautiful and slightly hypnotic. (Game was built in a day of slower CPUs. The blockiness of the simulation reflects this.)
