did anyone mention
global_settings { number_of_waves Count }


#declare RippleNorm =
normal {
  average
  normal_map {
    [0.9 Bigripple]
    [0.8 Smallripple]
  }
}

3.5.11.35  Waves
When used as a normal pattern, this pattern uses a specialized normal
perturbation function. This means that the pattern cannot be used with
normal_map, slope_map or wave type modifiers in a normal statement.


OK now I'm just a little ichy ... grain of salt eh?
