Use in expressions to get texture Eg: fractal sums 1/f noise: rock, mountains, ... 1/f abs(noise): fire, marble, clouds, ...

Noe I'll go through a series of examples to show how you can use noise within simple expressions to make cool and natural looking textures. By varying the terms in the expressions you can get a wide variety of effects, including rock, mountains, wood, fire, marble, smoke, clouds, water, stucco (oh, can you get stucco...), lava, skin, oil films, and many others.
