Translucent pebbles rotate over a textured background. Phase, variance, speed, range and offset are controlled from the initial has value.

Features:

Speed - The rate of change. Faster is more common.

Phase Rates - The speed at which each layer of pebbles grows and shrinks. Both possibilities are equally likely.

Rotation Rates - The speed at which each layer of pebbles rotates. Both possibilities are equally likely.

Colour Style - The range of hue values, curated around a central point. Monochrome or limited range palettes are more common.

Range - The overall size between which the pebbles oscillate.

Size - A representation of the number of pebbles in each layer.
