A visual overview of the concept of Pop-Up in architecture, design and art. The Pop-up generation is the youngest generation of designers who easily shift between the 2nd and 3rd dimension, between acting in the physical and the virtual world, they love transitions and constant change so their manifestations and designs are often temporary. They pop-up and then vanish again. Edited by the trend forecaster and visionary opinion leader Lideweij Edelkoort.
