This was damn cool. Watching and listening to it I wonder what is the hardest. Producing video with a sound chip or producing audio with a video chip. Fun stuff.
You can plug in any analog audio source into analog video (crt, video mixer). You can even mix audio + video using two resistors and have the music distort the video source. Another fun one is ‘no input mixing’ using a audio mixer (plug in output to input to get interesting feedback). Wonder if that would work with video mixers mmm
The problem you'll almost immediately run into is that modern computers typically use digital video streams rather than analog streams. You'd need to use VGA for the audio part (and that's making a lot of assumptions about the ability to send arbitrary stuff on it, I'm not exactly sure these days), and I'm not sure what readily available component could even be used for the video part.
Sure, but there are slightly more modern systems that still had analog composite video and audio output which had a lot more power than a 6502-based C64 - like the 680x0-based Amiga. Also, other systems may not have had the C64's bandpass filter on the audio which induced the bluriness in this demo.

I thought this would be a post about the messaging service and current politics in the US.
Much nicer! Very cool demo!
I'd love to see (and hear) what happens if you send the same signal through both video and audio.
Probably not as nice as this demo, but I'm sure there must be some signal combinations that yield interesting results.
I... might have to try that. :)
For others like me confused as to why there's not a video example on the page: click the youtube link in the first sentence!
Super cool mesmerizing effect.

I love the hack value, this is the kind of content I am here for!
has anybody tried this with a modern computer, can that get more horsepower out of audio-video?

What a beautiful thing to do
I’d like to see & hear the correctly plugged version of the video.

My first reaction too, but...
