I am referencing Reddit's april fools 2017 joke, where they made a subreddit called place. It was a 4k by 4k pixel area. You could place down 1 pixel of a single color, and you have to wait about 5 minutes to do it after each time. Some people even formed groups dedicated to making specific shapes and symbols, like the "Rainbow Roaders"I think they were called. This image reminded me of that.
