I like a lot Marge's idea. Besides that, what about singing and uploading parts of a song in order? i.e. Pokemon's first opening theme. Who knows, Nakama may even have a hymn some day! If it's too bold, maybe drawing the same way, each one expanding a little more the same general idea? Even better, creating a picture book; each member could draw a page, telling a story (sort of like Marge's idea, I realize).
