The Visible State of the Union

For the history buffs in the audience (and I know I've got some), here's a really cool tool that lets you use a slick graphical interface to search all the state of the union addresses by every president. It gives you the full text of the speech, as well as the frequency of the most-used words in each address. Notice how the word "throbbing" jumps to the top of the list during the Clinton years.
