Urban hacktivist Florian Rivière came up with this guerrilla crosswalk in his home town Strasbourg. Made from old carpet, the light-weight pop-up crosswalks are easy to carry and can be placed on the street “so you can cross wherever pleases you”.
Rivière explains that his walkway takes up the idea of roll-up codes in a video game to move from one place to another. The guerrilla crosswalks are for sale for €10. As of Monday, the artist sold two to art lovers. I believe that a pop-up crosswalk system could be pretty useful in temporary situations, such as big events and festivals.
