The Guardian is out with an interactive tool that allows you to choose your own pope based on the criteria you specify. First, it asks you to specify your ideal pope's age: old, very old, extremely old, and two feet in the coffin. Then it asks you to add any number of characteristics to help you narrow down your search. One fun game to play is to see if you can arrive at your ideal pope and have him not be a white European (without deliberately avoiding that option).
Try it out!
