Facebook and Foursquare both have real-time maps of polling place check-ins across the country, broken down by state. Facebook’s map runs on autopilot: Load it up, sit and watch, almost like an iTunes visualization. Blue dots show a polling place check-in, while a counter above tallies the total check-ins. The map can also be switched into an impressive full-screen view.
