I really liked this one. I actually used this and another of your tutorials as examples for a scene that I did, which you can find here:

As usual, great work! It's fun to learn, play and experiment with your shaders and "discover" the magic of Blender. Just a beginner question: Is it possible to animate the scale settings of the noise shader?
