This is quite cool:
It uses the information from your FamilySearch account (if you don't have one, you should get one -- it's cool) to see how you are connected to various groups and people, from early LDS pioneers and prophets (it IS done by BYU, of course) to European Royalty and Famous Americans.
I found out that William Bradford, of Mayflower fame, is one of my grand-uncles. And I'm directly descended from kings of England, Portugal, and Hungary. So turns out I'm a princess after all. :)
