Try it - it's very simple!

Some mesh is created this way:

   #include "functions.inc"
   isosurface {
      function { f_mesh1(x,y,z,0.05,0.02,1,0.01,1) )
      }
      contained_by { box {-1,1 }  // container shape (way to big in the
y-direction - too lazy to type more)
      threshold 0.02
      pigment {rgb 0.5}
    }

You'll have to adjust those 5 parameters, as I copied them out of one of my
scenes (definitely no speaker grid). And you would have code that fold
somehow (should be not to hard by substituting the y and z parameters by
some math.

Not that I'm saying isosurfaces are the answer to everything - your grid
looks very good the way it is. But there are many people who seem to fear
isosurfaces as something complicated.
