Temporary sculptures are artistic works that exist only for a limited period, prioritizing process, transformation, and ephemerality over permanence. Rather than presenting a static, enduring object, they unfold as events or actions in time, often involving materials or situations that change, decay, or disappear. In Roman Signer’s practice, temporary sculptures manifest as sculptural experiments shaped by natural forces—gravity, explosions, water, or movement—where the form emerges from the action itself. These works challenge traditional notions of sculpture, proposing instead a dynamic, time-based experience that embraces unpredictability, humor, and the beauty of transience.
