On Friday, Reddit unveiled Place, the latest in its streak of annual social experiments celebrating April Fools' Day. On Monday morning, Place came to an end. Here's how it went.

Basically, Reddit Place was a huge, collaborative canvas accessible on Reddit for desktop, iOS, and Android. It's almost like a massively multiplayer Microsoft Paint, where every Reddit user gets to paint one "tile" on the canvas every five minutes. That time limit means that users are forced to work together to do anything more meaningful than a random scribble.

Reddit rose to the challenge. At the time of its grand finale, Reddit tells Business Insider, over 1 million Reddit users had painted more than 16 million tiles on the Place canvas. Immediately before the end, over 90,000 users were simultaneously viewing the canvas and placing tiles.

What they came up with was pretty amazing. Here's the final state of the Place canvas:

Note the Mona Lisa, the bizarre "Star Wars" monologue, all the flags, and a bunch of little details. Reddit

One user made this time-lapse video of the entire Reddit Place experiment, start to finish:

Like Reddit's previous social experiments, The Button and Robin, Place has caused the link-sharing site's users to turn against one another. Individual "subreddit" communities are staking claims to different areas of the canvas, resulting in turf wars as each group looks to expand the size of its project.

For instance, check out this user-made animation of a key battle over the American flag as other users tried to paint over it:

Drama erupted as the players of popular online game "osu!" took over a chunk of key real estate, near the bottom of the screen, briefly turning the canvas into an "osu!"-versus-everybody-else war. That battle was visualized by a Reddit user as a 3D map of where tiles were placed:

All in all, it looks like Reddit had another successful April Fools' experiment. And this time, there's a finished product to admire.
