Procedural texturing capabilities are built into the fluid container. (You can texture using normal methods, but sampling can get slow for high quality rendering and it is not adaptive.) You can apply the built-in noise textures to both dynamic and non-dynamic fluid effects.
By animating textures set for non-dynamic fluids, you can produce beautiful effects that take much less time to render than dynamic effects. This is an efficient way to create cloud effects, for example.
