While the pictures are pretty, fluid simulation has a lot of practical applications. Or, you can just use the kitchen sink. You can even do simulations with ASCII output if you like.

But remembering that air is itself a fluid, [Desi] took his simulation from the computer to the sink in order to better visualize what his cooling duct was doing to the airflow.
