Ben Fry's zipdecode and anemone: Visualization apps

A friend and I were surfing Ben Fry's site today, where we played with these interesting visualization experiments.

zipdecode (requires Java), a nice little visualization tool that Fry created to learn how the zip code system works in the U.S. When it loads, click on the map to activate it and start typing the first numbers of zip codes one at a time. Would be nice if it also included a way to zoom in to understand what geographic area (state/town boundaries) you are looking at.

anemone (requires java) is an example of organic information design that gives a visualization of the changing structure of a web site, juxtaposed with usage information.
