Family yearbooks. Why didn't I think of that?? Since most people don't print out pictures like they used to, this would be a great way to document your years in pictures and still have hard-copies to look through/show people.
I'm not a big fan of paper clutter, but I want to preserve my children's artwork somehow. Taking pictures of artwork is a great solution - it's space-efficient, portable, and gives you options for displaying that artwork later.
