On the steps of the National Portrait Gallery, Washington, DC. This taken with my Holga (I think), on one of my lunches. My gym is right across the street. Lately, I’ve been thinking about cities and use cases….

I’ve also been intrigued by this new social media service called Gowalla. Have you heard of it? An interesting integration of interaction design with the urban space. What it basically amounts to is the human equivalent of a dog’s pissing on a tree to let other dogs know he’s been there and to mark his territory.
