Taking the curl of a noise field will get you a divergence free flow field[1]... which is an easy way to get something that looks like fluid dynamics, but isn't

Taking the curl of a noise field will get you a divergence free flow field[1]... which is an easy way to get something that looks like fluid dynamics, but isn't. I've use this to great effect on the surface of a sphere to generate textures for gas giants[2].
