Fluid Dynamics - Curl Noise

I’d wait a bit before releasing so we can add some extra features as well. Compound clouds are a massive improvement but alone probably don’t quite constitute a whole new release. If we’re going by this list, there are still a few things to add.

Also, how difficult will it be to have the fluid simulation move the microbes? It doesn’t have to be added now, but eventually we’ll want microbes to float along in the current and only be able to fight against it if they have flagella/cilia.
