Remember the egret painting posted to reddit a couple of weeks ago that everyone then painted in recursion style? Artists were churning out new versions so fast that you couldn't keep up with them, and multiple artworks branched off from the main iteration. So of course, a subreddit community was created to archive them all. Redditor nublargh made a diagram of the paintings, arranged so that you can see the relationship between each one. That's 24 paintings over nine generations, as of now, but it may be updated.
You can double click on each thumbnail to bring up the full-size painting at its reddit post. If you prefer, you can see a lot of the photos quickly in this Twitter thread. -via Metafilter
