Does anyone have a creative suggestion for making home made photography book containing doorway images?

I am an adult student in a photography course. Recently I learned that the home made photography book ignment must be highly creative book that reinforces the theme of the images contained. Prior to learning this information I was prepared to create a basic simplistic book. I am looking to see if anyone can suggest a creative way to prepare a photography book utilizing doorway images. If anyone has any questions please don't hesitate to contact me. Thank you.
