The Collapse of a Microcosm is a site-specific sound and light installation that enacts a process of remembering and reconstructing. Dozens of photosensitive light sources equipped with tiny speakers, arranged in a multi-layered circle, accumulate data from sunlight and gallery interactions, then replay it to the next, forming a one-day memory. Each memory vector is represented by a tone, sonifying the difference between now and the past is transformed into a low, resonant hum, weaving time into a flickering sonic tapestry. This breathing architecture of photons and vibrations immerses visitors in a shared nexus of environmental changes, bodily presence, and technological memory. The Collapse of a Microcosm highlights the liminalities of perception and transition inviting a reorientation of worlds by dissolving boundaries between the organic and the artificial—revealing a very resonant, and very different, ecology.
