Principle

The canvas is constantly redrawn in itself, applying slightly rotation and scaling effects first.
The parameters on the page allows to change the rotation speed, the scaling amplitude and frequency, and the starting angle. The result follows the chaos rules: the tinyest change in the parameters and the tinyest change in the computing speed might totally change the result.
