Image idea

Woke up early this morning, with the thought of creating some kind of big internet-based image.
I would start off with a 100×100 pixel pattern or image, and ask four people to create another image, but only by seeing one edge of my starting image. They would then build their own 100×100 image, using my one edge as a starter for theirs. They would then get three more people to create images, using just the edge of their picture as a starter and so on… each picture would get submitted back to me, putting together one huge picture.
