This brilliant app has been launched to coincide with Global Street Art's first book 'Concrete Canvas' (its called simply 'Global Street Art' in the US). When you point your device at the front cover of the book the app launches an amazing augmented reality feature where a giant spraycan rises out of the book. Other features include a slideshow sample featuring content from the book and the city augment, where a city rises from the ground and builds itself.
Use the cover of the book to trigger the app, the link is below.
