Infrastructure Observatory (IO) is a “community devoted to exploring and celebrating the infrastructural landscape.”
Their mission: “to render visible the oft-invisible guts of modern life, and foster chapters of enthusiasts around these structures throughout the world.”
The group recently came out with this pocket-sized waterproof book about “shipping containers and the corporations that own them” (The Container Guide, 2015). They also held MacroCity, a cool-looking group of critical panels and city infrastructure tours wrapped into one conference.
Their main page is a little with interesting photographs of urban infrastructure — check it out. As of right now (late 2015), they are — somewhat obviously — set in major metropolitan areas: San Francisco, New York, and London. However, I’d love to see, in the future, groups like this China, India, or elsewhere.
