Personally, I use a height_field for simulating ripples. However, I have 
not, as yet, come up with a really satisfying and good-looking one. It would 
be mainly finding a good function describing a ripple field (as well for 
height_fields as for isosurfaces), but that is a little beyond my 
capabilities. Have you looked into Mike Williams's Isosurface Tutorial? I am 
not sure, from memory, maybe something is there.
