The MAPHAVE 1 app - acronym for «Ministère des affaires et patentes humaines, animales, végétales et élémentaires» - activates a series of "diminished realities" that can be visited at nine locations in downtown Montreal. Positioning himself at specific points, marked out at each of these locations, the user of the app will explore, on the screen of his iPhone, a landscape rebuilt from an interactive panorama of sounds, texts and images. Each site has been reinvented by a citizen or frequent user of this area, in collaboration with artists Claire Dehove and André Éric Létourneau, co-directors of the Ministry. The actions of MAPHAVE will continue and extend to various cities around the world. This project is presented by Les Escales Improbables de Montreal, in collaboration with Le Partenariat du Quartier des spectacles, UQAM (PAFARC, HEXAGRAM, GRMS) and LOPLOP.
