Warning: Before you click 'play' on this video, I recommend that you turn the volume down, because the music is jaw-droppingly hokey. Aside from that, though, I think this is pretty cool--a kind of time-lapse emotional thermometer of the United States as it endured Hurricane Sandy. The video is based on a computer analysis of the "location, intensity, and tone" of Sandy-related tweets, according to the Facebook page for the Global Twitter Heartbeat project (a collaboration between the University of Illinois and Silicon Graphics International). Second warning: They freeze the action right before Sandy makes landfall, milking the drama. But it's worth the wait, IMHO.
