>"Freespin is a Commodore 1541 demo, released in 2021. It runs on the Commodore floppy drive. It is is the first demo on this device. [Without the C64 attached!]

[...]

Freespin generates sound/music using the floppy drive mechanic (in particular, the stepper motor responsible for moving the head to the right track).

Video is generated through the [1541's] serial bus."

PDS: Absolutely amazing!

I have never seen this done before!

Floppy drive music is pretty impressive, see also Floppotron: https://www.youtube.com/c/Pawe%C5%82Zadro%C5%BCniak

(they've got some non-floppy devices like scanners too)
