Badges: Add badges for # of different countries user has seen movies from

I think a cool badge idea would be to have one that tallies the number of different countries you've seen films from. I know from according to letterboxd that I've seen movies from 84 different countries. They show it in the form of a world map, but I think on IMDb it could be easily done in the form of a simple badge with the number in the middle. It would be an easy way to offer the same functionality of someone in the same movie space with a minimum of effort. Just an idea that I thought would be popular with foreign film aficionados.
