It was something we tried a while back. It's where there is a theme and someone makes a fairly large piece based on the theme. Then they send the PSD to the next in line, and they add a transition on the side and add to the art, basing their part on the part before it.
So the first could be fish, then sea, then land, then air, then airplanes, and eventually it will get off. Like the constantly changing sentence. :P
