Yes, heightfield is a good candidate.

I also think that an isosurface using one of pov's internal functions 
should also do the trick.


#declare plain = height_field {
  function Res,Res {
    <<function here>>
    }
   smooth
   translate <-0.50, 0, -0.50>
   }


All that's left is to find the right function and parameters ;)

Simple combinaison of trigonometrics functions and/or f_ridged_mf() can 
be used as a base.
