How to distort Voronoi using LibNoise

Hi, first, sorry for bad English. ;) (I need at least one answer (I now this question can be hard to ask, but please, try to answer, thanks :) ), so I will try to explain as clear as possible, if you don't understand something, you can ask me by comments ^^)

Well, I'm making some tests with LibNoise, and well, now I want to distort Voronoi.

The explanation (of all the thing I made)

First, I started searching "Voronoi Libnoise" in Google, and I found this image:

Then, I started to read the website, the tutorial says this:

 DistortedVoronoiBiome(X, Z) := VoronoiBiome(X + PerlinX(X, Z), Z + PerlinZ(X, Z))

That means that mixing Perlin in the Voronoi Algorithm you get something like the image #1...

So having this information, I started searching in LibNoise how to do this, and I found Turbulence class (that uses Perlin Noise), and this what I did:

 Texture2D tex;
 int size = 512;
 float power = 1;
 
 void Start() {
     Generate();
 }
 
 void OnGUI() {
     if(tex != null) {
         //Display tex...
     }
 }
 
 void Generate() {
     tex = new Texture2D(size, size);
     var gen = new Voronoi();
     var mod = new LibNoise.Operator.Turbulence(power, gen);
     for(int i = 0; i < size; i++) {
         for(int j = 0; j < size; j++) {
             float c = Mathf.Abs(((float)mod.GetValue((double)i, (double)j, 0)));
             tex.SetPixel(i, j, new Color(c, c, c));
         }
     }
     tex.Apply();
 }

The problem

The problem is that I don't get the desired effect, I only get this:

The cell's shape don't change, only the border of the cells get granulated, so, I need to know how can I make something like the image #1...

Other things I tried

I tried, other classes like Displace and Terrace, without luck (I only get the same effect), maybe I'm not using it correctly, so I need some help about how can I figure this out...

Any suggestions?

Thanks in advance. ^^

Bye.
