Physis is an installation where art, technology, and nature converge. A granite block, split in two and set on a track, slowly opens and closes each day, powered only by solar energy. The movement, imperceptibly slow and weather-dependent, reaches its peak at midday. Entirely off-grid, Physis follows the rhythm of the sun: active on clear days, still during rain or snow, and resting at night. It breathes with the world, echoing the quiet life cycles of plants, shells, and stones.
