Yes, I built a really bad version of it a while ago: https://braeden.dev/waterfall/

Click waterfall, and then click play when you have the audio on your computer playing outloud.

If you play the audio outloud, your mic should be able to pick up a barely recognizable version of the picture (try the heart first to calibrate the "row delay").

Take a look at the example pictures on github ^, poor, but functional fully web version.

Amazing work! Knocked it out of the part. Have you checked out the other guy's example in the same subtree from the comment you posted on? Curious your take on that work. Keep it up!
