I've mentioned it before, but it's been updated since so it's worth giving props to again. It's the latest version of Ben Fry's ZipDecode interactive US map, where you can pinpoint a particular location in the US by typing its five-digit zip code.
It now draws the map a bit slower at the start so you can see the country light up piece by piece, and you can opt to zoom in on your location as you type the zip code digits. Pretty cool stuff; go check it out.
