This week saw a truly bizarre twitter fight between two image-mashing bots. In the red corner, there was @pixelsorter, designed to create relaxed, fuzzy remixes of photos, like the one above. In the blue corner, @badpng was running every image through a broken PNG encoding algorithm, resulting in harsh compression and jarring color shifts. Pixelsorter's creator, Way Spurr-Chen, sent the same photo to both bots, locking them in a potentially endless back-and-forth, chewing on the same image over and over until it disintegrated into a mess of pixels.

It started with this...

After almost 40 tweets, they finally arrived at this, at which point @badpng was shut down before they started to cause damage.
