Gaseous

Fluid dynamics are ephemeral in nature. They generate structures and forms that are constantly changing, continually transforming. The ripples that appear on the surface of water after throwing a stone, the sinuous movement of a fire flame or the dissipation of smoke... These are examples of how gaseous masses develop, giving rise to an infinite number of morphological possibilities.

In the field of computer-generated graphics Noise patterns are generated by an algorithm, whose control is procedural. In this way, a randomness similar to what Nature generates, can be achieved.
