Tokyo, Kyoto, Washington, D.C. and Chicago join the shelf: the Rainbow Bridge, the torii of Fushimi Inari, cherry blossom on the Tidal Basin and the L over the river.
A shelf of pop-up books, one for each of the world's great cities.
Open a book and the city rises out of the page: towers stand up, bridges reach across the river, palace roofs lift into the sky, folded the way real paper pop-ups fold. Lie it flat and the day turns to dusk, the windows light up one by one, a music box plays, and the city comes alive: Big Ben chimes, Tower Bridge lifts for a tall ship, mariachis strike up on the canals of Xochimilco, the L rumbles over the Chicago River, the Golden Pavilion shines in its pond in Kyoto, lanterns glow in Seoul, the sun sets behind Barcelona.
MADE FOR IPHONE DUO
On iPhone Duo, the phone is the book. Closed, its outer screen shows the cover. Unfold the phone and the book opens with it: slowly, and every card stands up exactly as paper would; snap it open, and the whole city springs up. On any other iPhone, a hinge at the bottom of the screen opens the book.
ELEVEN CITIES ON THE SHELF
• Barcelona: the Sagrada Família, Casa Batlló and Park Güell. Free.
• Chicago: Buckingham Fountain and the skyline across the harbour, the bandshell in Millennium Park, the river and the L.

Every book is printed in the style of an old atlas: cream paper, gold-foil covers, map pages with compass roses, and a little paper plane that travels with you from city to city.
TURN THE PAGES
Drag a page to turn it, or tap its edge. Rock the book and the city answers: boats rock, lanterns sway, the plane swings wider.

Barcelona is free. Each other city is a one-time purchase. Or get Every City: every book on the shelf, and every city we add, forever.
