A group of researchers has attempted to visualize the mood of the nation over a 24-hour period using a cartogram mash-up of tweets and population data in Pulse of the Nation.
"Not only did they analyze the sentiments we collectively expressed in 300 million tweets over three years against a scholarly word list; these researchers also mashed up that data with information from the U.S. Census Bureau, the Google Maps API and more. What they ended up with was a fascinating visualization showing the pulse of our nation, our very moods as they fluctuate over time.
The researchers have put this information into density-preserving cartograms, maps that take the volume of tweets into account when representing the land area. In other words, in areas where there are more tweets, those spots on the map will appear larger than they do in real life."

Here's an interesting graphic for you map and data lovers, based on geotagging Flickr data:
"Blue points on the map are pictures taken by locals (people who have taken pictures in this city dated over a range of a month or more).
Red points are pictures taken by tourists (people who seem to be a local of a different city and who took pictures in this city for less than a month).
Yellow points are pictures where it can't be determined whether or not the photographer was a tourist (because they haven't taken pictures anywhere for over a month). They are probably tourists but might just not post many pictures at all."
There's a whole set of them for various cities.

Facebook is considering making the app official. Hackathons are events where programmers get together to collaborate and share ideas.
