They're bicubic patches. First I choose a direction for the wind, then push
the control points in that direction semi-randomly. The top corners are not
touched, to give the impression of being anchored. I wrote a macro to
generate them given basic parameters (size, degree of perturbation etc). It
probably looks a lot cleverer than it is!
