For April Fool’s Day, Reddit ran a subreddit, r/place, that let users edit pixels in a 1,000 by 1,000 blank space for 72 hours. Users could only edit one pixel every ten minutes, which forced patience and community effort. This is the time-lapse of the effort.
Kind of great. It’s fun to watch the edits of thousands converge. It’s a complete hodgepodge but it all fit together in the relatively small space somehow.
See also the edit heatmap by Reddit user JorgeGT that shows the number of edits per pixel.
