m.rm.r. (mormorio in Italian, mrmr in Slovenian) is an interactive installation on privacy and AI-based citizen monitoring that takes as a perspective the ambivalent relation of Trieste to both blocs during the cold war era. Starting from a taboo subject in Trieste (the attitude of Triestini towards Tito’s Yugoslavia, especially in the 50’s), yet also the existence of a “small Berlin wall” in Gorizia through which many people fled to the West, the project aims at re-staging European imaginaries about the iron curtain by giving voice to Triestini themselves. Yet as talking publicly about it may be risky, the installation uses a reverse, ironic point of view: miradors diffuse these taboo conversations with a loudspeaker but as soon as a spectator comes close and tries to eavesdrop, miradors suddenly shut up; being equipped with AI-monitoring proximity sensors they can indeed detect any human movement in their surroundings. A dozen such devices are installed in Miru Park, Kantovel, during on the edge 2023 event.
