Peffisaur is a free, multiuser MMS weblog, but it also offers its readers to take part in some kind of collaborative art.

Pictures posted on Peffis are randomly distributed over time from several users all over the world. Peffis makes what it calls “a cloud” which melts down these images into an increasingly chaotic single one.

The meltdown, where new images are added to the old image, is done once every hour so the image seen on top of the page is constantly changing as people add images to the site.

A copy of the current cloud is also saved every month on day one.
