Unfold Your City — pop-up books of great cities

Pop-up books of great citiesOpen your phone, and the city rises out of the page.
Open the phone, and the book opens with it.
On iPhone Duo, the hinge is the book's spine.
The city rises out of the page.
Every card stands up exactly as real paper would at that angle.
Lay it flat, and dusk falls.
The sky deepens and the sea turns to ink.
The lights come on.
A music box plays, and Barcelona comes alive. It's the free book on the shelf.

Made for iPhone Duo

The phone is the book.

Shut, the outer display shows the city's cloth cover, stamped in gold. Unfold the phone and the book opens in your hands: slowly, and every card stands up at the true angle of the fold; snap it open, and the whole city springs up.

On every other iPhone, a hinge at the bottom of the screen opens the book, and in AR you can set it down on a real table.

Twelve spreads, four cities

A day in each city.

Every book opens on a panorama of the city, then two of its landmarks, from morning light to golden hour. Lay a page flat, and it turns to dusk.

The traveller

A little paper plane goes with you.

It circles a tower on a line, rides a cable car up Namsan and lands beside a guitarist in Park Güell. Look for it on every page.

Real paper engineering

Every card stands on a real fold. The book is tested at every angle, so no card ever passes through another.

A music box on every page

Each spread has its own little tune and its own sounds: bells, ferries, a gayageum. All of it made in code.

Rock the book

Tip it, and the city answers: boats rock, lanterns sway, the plane swings wider.

On your table

In AR, set the book down on a real table, walk around it and turn its pages.

Printed like an old atlas

Cream paper, gold-foil covers, compass roses and italic place names, all drawn from scratch.

Quiet by design

No ads, no account, no tracking, no data collected. And VoiceOver reads every page.
