And there’s also a Lorenz visualizer. This visualizer is based on the Lorenz equations. The Lorenz system is a system of ordinary differential equations first studied by Edward Lorenz. It’s notable for having chaotic solutions for certain parameter values and initial conditions.

The Lorenz rotates on the screen based on the volume of the left and right channels. The colors are calculated by going from the two centers points to the edges of the screen.

The volume also controls how large the Lorenz grows, higher volumes generate more points and cause the Lorenz to rotate faster.
