Modeling squares isn't exactly very exciting.

I remember some kind of cave city project, where people could model objects and things from an image that had all kinds of stuff in it. (or design their own little cave section? I can't remember)

I think the most fun would probably be to do a some kind of birds eye view scene like pic related, where everyone can do different parts of it and add their own flavor to it. You'd just need to provide the ground plane and some kind of measurements to help people scale their models.
