The Scramble function distracts the texture by overdrawing it with a combination of circular sprites. These sprites are cropped from the texture itself. You can use it to render basic, homogeneous materials from images. The materials will feature the same colors like the source images.

Increase the Octaves value to change the result from blurry (Image 1) to crisp (Image 2).

You can also employ this function to create animated, fluid textures. Keep the Seed parameter at a constant value and increase Time Offset.
