The previous time I visited London’s Tate Modern museum of international modern and contemporary art, the view you see pictured above wasn’t possible. That’s because the museum only recently opened a building to provide more room for exhibitions, more spaces for other uses, a restaurant and an observation deck allowing for sweeping, 360-degree views of London. (If you plan to go, bring a sweater, as it can get gusty up there.)

Back inside, warm and cosy, I wandered into an exhibition called Living Cities, which explores how urban dwellers live. It uses photographs, paintings, interactive art and such displays as the construction you see above — a scale model city made of couscous. (I wondered what it was made of when I smelled it. I was surprised to learn my guess was correct.)
