As part of my BTS, I created an animated poster for the the Metropolitan of the city of Montreuil. The purpose was to create an interaction between citizens and their city. On the poster a score appears: it is a game that users can download on their phones by scanning a QR code. Once the game is installed, the user, with the help of a dictionary, can test his/her knowledge about the specific language of Montreuil with two mini-games.
