It was actually a pretty cool site. You would reserve one of the free square "tiles" and would only see a thin stripe of the neighboring tile that you'd paint next to. You'd get a png image with something like 10 pixels of the neigboring tiles on the edges, that you had to blend into, and given 24 hours I think to reupload to the site. Only when all 4 neighboring tiles were completed a tile would be revealed. It was a lot of fun. They also had stuff like imaginary gold coins for X number of painted tiles, not for yourself, but that you could award to a tile you especially liked somebody else made.

I also like the art in the sense that it allows all kinds of perspectives to flow into the image, and there is a way greater complexity than somebody alone could create. It would be worthwhile to recreate the site - maybe I'll do it some day (-:
