It’s a Sin is an immersive installation for MIAD 2024, transforming a created, deconsecrated-church-like space into a multisensory, emotionally charged journey where each of the Seven Deadly Sins is expressed through social media and linked to the Sustainable Development Goals. A contemporary Via Crucis guides visitors through interactive video, dynamic light, sound, tactile environments, bespoke design, and Butoh performance, orchestrating reflection, catharsis, and ethical awakening in participatory, layered micro-universes confronting human flaws, digital culture, and global challenges.
