Germany has divided opinion at the Venice Architecture Biennale by inviting visitors to wander around an empty pavilion and experience digital content via QR codes.
Called 2038 – The New Serenity, the presentation consists of a virtual "Cloud Pavilion" accessed by pointing smartphones at matrix barcodes on the walls of Germany's neoclassical exhibition venue in the Biennale Gardens.
Visitors can then watch movies on their devices that explore how the world could be in 2038.
The exhibition was curated by an international team of over one hundred architects, ecologists, artists, scientists, writers, and politicians.
