Facebook holds hackathons quite frequently to continue to encourage the hacking culture that gave Facebook its start in the first place. Now that we are coming up upon the end of the year, Facebook has taken a look back at all of the hacks generated during these hackathons and have picked their favorites.

One of the especially cool ones is pictured above. Facebook engineer Paul Tarjan was inspired by a conversation during a flight. The person next to him explained how people in a part of Michigan were actually Packers fans. He hacked together the view seen in the picture above, which correlates NFL team Likes with the counties of the people who liked the team on Facebook.

He found that the girl was right, and also hacked together a pretty interesting visualization of some of the data Facebook has available. Head on over to the source link to check out all of Facebook's favorites.
