This is a way to listen to changes to wikipedia. You are literally listening to knowledge being added to the world.
Pluck sounds are an addition, strings are subtractions, and the pitch says how how big the edit is. My heart shudders at this I love it so much.
Oh my gosh the orchestral thrum (I don’t know what that’s actually called; I’m not musician) when a new visitor joins is hair-raisingly gorgeous!
I have this on in the background, doing other things. It’s gorgeous.
So, this is actually pretty amazing. Unspeakably relaxing, and also really strange and lovely.
