An American football pitch as a skateboard ramp and the Aya Sofia as a rollercoaster: the images by Turkish photographer Aydin Büyüktas are literally mind-bending. After going viral, they are now finally also available in book format, including entirely new images and a making-of, which shows the photographer's working methods with drone technology. His brainchild Flatland is named after Edwin Abbott Abbott's satire book about a two-dimensional world populated by geometric figures, from which certain parts have been included in this book.
