The Blobs function combines randomly placed ellipses to a fractal pattern. You can use it to simulate natural textures like rock or organic materials.

Control the number of the blobs with the Elements Count parameter, the size with the Elements Size value. Use a large blobs size (>50%) to get the typical fractal appearance of the function.

The Amplify value controls the inner contrast of the function. The higher you set this value, the more chaotic the result will be.
