Damon Darlin at the Business 2.0 blog pointed me over to the Musicplasma site which I think is one of the coolest social networking mapping web-apps ever.

Type in a artist name. Hit SEARCH. It maps out the connections between that artist and all other artists in a great visual map. Click any other artist on the page and the graphic shifts to make that artist the center of the map. It’s AWESOME.

Now if only I could do this dynamically with my contact list instead of trying to do it myself manually with OmniGraffle, which is very cool but very time-consuming and slow.
