Strange Attractor on an Etch A Sketch with Raspberry Pi Pico

Each stepper motor is controlled by 3 PIO state machines, fed by 3 DMA channels (one for motor direction, one for motor speed, and one for number of steps). Motor speeds are calculated according to the Lorenz equations to draw the Lorenz curve.

Video sped up 60x.
