Actually, you don't need my include file to accomplish that. POV-Ray has 
some special functions in functions.inc. One of them can produce 
honeycomb-like patterns. Check this out:

// begin code

// If using 3.7, put +fng at the command line for 16-bit gray scale.
// If using 3.6, uncomment this line:
//global_settings{hf_gray_16 on}

#default{finish{ambient 1}}

camera{
  orthographic
  right x*2 up y*2
  location -z*100
  look_at 0
}

#include"functions.inc"

plane{z,0
  pigment{
   function{
    f_hex_x(x,y,z, 0)
   }
   color_map{[.7 rgb 0][.9 rgb 1]}
   scale .25
  }
}

// end code

Not at all! Sometimes we tend to over-think our problems, and we don't 
know all our options.

I encourage you to continue reading as much of the documentation as you 
can. This way, when a problem arises, solutions will start popping up. 
POV-Ray is one of those programs that lets you accomplish many tasks in 
several different ways.

I released some hexagonal patterns a while back, you might want to check 
them out:

Happy Raytracing,
