Canvas — A collaborative annual pixel placing event for the Fediverse!
I could see a permanent one working with a different model. Like 1 pixel per hour with a fixed drop rate (instead of this "stay and place as fast as you can for best performance"), and you can hold like 36 pixels. Once a month you move the canvas 200 pixels to the right, so the leftmost zone slides into read-only-world.
