This is a really cool technique for making 'turbulent' procedural elements in shaders.
See the paper 'Curl-Noise for Procedural Fluid Flow':

the fractal potential stuff looks like it would be interesting for terrains, I doubt I'll be able to use the paper myself a priori...

Yeah, it could work quite well for simulating eroded terrain.
I think voronoi cell edges perturbed using curl noise would work well as river beds etc..

why make me droll oh why
erosion thats what I saw, my terrain shader has got an erosion parameter but this curling introduces flow. I'm unable to implement finite methods sadly...
well reading my mind is a no brainer here
