If you ride fixed and have access to the internets, you've probably been on Fixed Gear Gallery. It is a great repository of images of fixed gear bikes around the world. Today, my Surly Steamroller has joined the Great Archive as bike number 5042 (42! for you Douglas Adams fans).
The New York Times recently ran a story on fixed gear bikes. The online version has a great slideshow with audio with different people talking about bike culture.
