I just built a dual spiral clock; one for the minutes and one for the hours. They are independent of each other, both driven by separate stepper motors but programmed with one Raspberry Pi Pico programmed in microPython. The spiral is an Archimedean spiral (AKA Arithmetic spiral) where the movement away from the center is the same for each degree of rotation. A video is at https://youtu.be/lb3w8e9-sAA
The design including the .py is shared at Thingiverse at: https://www.thingiverse.com/thing:6584614
The program is two nested "while" loops to send 12 sets of pulses to the minute spiral then one set of pulses to the hour spiral. Works perfectly.
Hope you enjoy it,
Bob
