TouchGraph Facebook Browser

Continuing the theme of interesting interfaces, check out the below screencap from TouchGraph Photos, a Java-based Facebook app which maps your friends and their relationships using coloured bubbles (and photos when your more zoomed in). It's similar to the popular Friend Wheel app (175,000 adds and counting) but with a slicker interface and a focus on navigating your friends' photos. They've employed the same interface in tools for exploring both Google and Amazon.
