The State of the Union in Words: A Look at the 34,000 State of the Union Words Delivered of George W. Bush It's only mildly interesting to me politically.

I love both the circles on the right to visualize hit counts and the way you can click on the highlighted words in the "text" of the speech and see the whole context surrounding the match at the bottom. Very clever and innovative if you ask me.
Play around with it for a bit. The "choose a word here" dropdown at the top is handy for search ideas.
