It’s a fediverse wide collaborative art project!. You follow the link, log in with your fediverse account (you provide your username, they dm you a code, you use that to login) and then you can start placing pixels to create your art. The purpose in my opinion is two fold: one, making art is fun in and of itself! And two: it’s fun to participate in a community event. The whole thing is practically an exercise in decorum and human nature, and will others graffiti your art piece or cover it up, or add to it?
I added three sprites. A buzzy beetle from Paper Mario, a jujimo from Stardew Valley, and a triforce from Zelda. No one disturbed my pieces, and a stranger worked on my triforce with me, without ever having to speak about it. It was thrilling! Somewhere else in the world, a stranger worked on a little bit of sunshine along side me and with me. It’s possible they don’t even speak English!. Very cool!
That’s not necessarily a false sense of privacy if it works. There’s an inconvenient barrier to searching vote history and if you do it in the current system you’d be recognized as petty at least. Easing access is not going to make Lemmy better.
