Here's a fun searchable map from the New York Times. Enter a street's name, and you can see how many other streets have the same name in other states. Based on Zillow data, you also get a quick comparison of estimated worth of houses on your street versus homes with the same street name but different suffix.
See also the word cloud version of the same data.
And finally, before you start going all crazy with word clouds in your PowerPoint slides, read Gregor Aisch's about design choice.
