Every year the largest and most important Rock festival in Latin America, the Rock al Parque, is held in Colombia. To promote this festival the city of Bogotá is decorated with posters, which are enhanced with a hidden Chameleon Code. Our Cee platform was used to create an amazing content which will appear when the coded posters are scanned. By scanning people are able to find the location of the event, directly follow Rock al Parque on social media, download their app, watch an exclusive video and even see the full festival programme. This innovative approach of promoting a festival already leads to more attention and engagement and will therefore lead to even more visitors.
