Check out this nifty little bit of flash art called ZoomQuilt. It's much better if you load the flash version.
What we have here is a collaborative creation, where there is an organizing principle (the red ribbon and some rules about zooming in and out), but each artist has built unique parts of the whole. I imagine that no one got into micro-managing the placement of doors on buildings, or the colors of the flying lizards, which is the sort of thing people like to do in corporate life. (Haven't we all been guilty at some point?)
However, there is also clearly a coordinator of the project, an artistic vision that links the whole, and other features of organization. I imagine this individual said something like "the viewer should experience worlds inside worlds, in a kind of moebius loop, following the red ribbon. Beyond that, you can do anything you want. Just get it in by Friday".
Role clarity, context, objectives -- all good things to have.
