Hi Alberto,

great job. IMHO the water surface needs some more fine structure.
Try a superposition of 3 ridgedmfs, where the next is about
1/3 or 1/4 scale of the previous each. Something like

         isosurface{function{y - myridgedmf(  x, 0,   z)} +
  0.3 *  isosurface{function{y - myridgedmf(3*x, 0, 3*z)} +
  0.09 * isosurface{function{y - myridgedmf(9*x, 0, 9*z)}

You may want to try different scaling factors.

I think this would provide for a nice animation as well,
shifting the 3 components with different speed (first one
fastest).
