It's a subreddit/event that they do every year (or I think it's only once a year?) where every user can place a single, colored pixel on a large digital canvas.

Your pixel can be over-written by another user, and each user can only place one pixel every 5 minutes or so (and there's a lot of bot-use, which is lame)

So different subreddits will band together to try and orchestrate a picture and protect it from being over-written by other users (or bots... if possible)

So alliances between subreddits are formed, fall apart, some backstabbing and deception... all until the event is over and the final canvas is locked-in.

It was actually a pretty cool event. You could maybe join a discord, a pattern and placement would be followed, and you'd just drop a pixel where it needed to be when you could, to help the overall picture. Or go rogue and try and etch a tiny little corner somewhere yourself

I had fun with it last year, but c'est la vie. I ain't going back there for anything. Would be cool if the different instances could somehow do something of the same nature across the fediverse one day. It was the comradery and light-hearted fun that really made it

Same, used to love it last time. But this time I won't participate.
