Here are two really cool articles about The Interval at The Longnow done by Dot & Bo.
The first post is a photo tour with descriptions about the bar itself and the objects within it. It is called tour the mechanical wonders of The Interval.
The second one is a photo essay interviewing us and the The Longnow foundation about the space, what it's for and what it means. This essay is wonderfully named: The secrets behind San Francisco's mechanical cafe.
Both of these are fun and worth a read.
