My most favourite demo is "Freespin" which runs entirely on a floppy drive without a computer. Crazy stuff. link to this video

Matthias Kramm demonstrates Freespin, a demoscene project that runs entirely on a Commodore 1541 floppy drive, generating video and audio.
Freespin is a demo that runs on a Commodore 1541 floppy drive. More information at quiss.org/freespin/. It generates sound/music by vibrating the drive's head, and video by switching the two serial bus lines between ground and +5V. A single 100 Ω resistor is used to connect the video. A C64 is used to boot the demo, but can be disconnected once it's running.Why it's here
2 people recommend thisWhat people say. Highly praised as an incredible feat of retrocomputing, running a full audio-visual demo directly on a floppy drive's hardware.

Here's a demo running directly on the 1541 disk drive. It generates video by hacking the serial cable that's usually used to connect to the computer, and audio from the drive motors. link to this video

The "C64" demo "Freespin" wires the drive's data cable directly into the monitor's data cable to play a demo (including audio!) without an actual C64 involved at all: link to this video

There's a demo that plays entirely out of the 1541, you can disconnect the rest of the computer: link to this video
