Pentagram's design for the epic Global Cities exhibition, which opened yesterday in the Tate Modern's monumental Turbine Hall, was built in 18 days. And they've got a movie to prove it. Learn more about the exhibit at Pentagram's site; here's the pitch on the show.

Global Cities looks at changes in the social and built forms of ten large, dynamic, international cities: Cairo, Istanbul, Johannesburg, London, Los Angeles, Mexico City, Mumbai, Sao Paulo, Shanghai and Tokyo. Drawing on data originally assembled for the 10th Venice Architecture Biennale, the exhibition features both visual art and architectural responses to explore these cities through five thematic lenses: speed, size, density, diversity and form.
