We need to make a Collab...

As you know are team is very new and not a lot of people know about it. So I was thinking we should do a collaboration on something to get our team well known. A lot of teams have been doing Rube Goldburgs, but I dont want to do that. We need to think of something that will make our team stand out and make people want to join. So post your ideas about anything you would like to make.
The only idea I have thought of is Making a game divided into parts and each member could make a single part of it. That is not the only idea I want though so more would be greatly appreciated!
