Displacement and phase cancelling technique used.

This technique (which is used in most of the other files) basically uses 2 identical noise nodes.
Noise A is displaced by Noise B. To achieve this, Noise B is transformed into a vector (by using a Composer node) which is then displacing the origin of Noise A.
Noise A and Noise B are then mixed (Combiner node in "Add" mode). Often Noise B is set to a negative value, which then cancels out parts of Noise A.

Sound more complicated than it actually is.
