Perlin Noise

Perlin noise generates pixels with values that vary between the foreground and background colors, resulting in a cloud pattern. Sometimes known as Clouds or Difference Clouds. It can be used to create realistic looking scalable textures, including cloud, smoke, and rock or earth-like effects, and is a great way of adding realism to textured areas.
