Based around the 20's avante garde cinema genre of the City Symphony, Seoul City Machine is a filmic poem for the urban landscape of tomorrow. The film is a portrait of a city where machines and technology are now the dominant inhabitants of space. Our guide to the city is the disembodied voice of its urban operating system software. Scripted and narrated by an AI chatbot the city machine voices its own creation story and explains itself to the citizens it affectionately manages.
