Japanese artist Fujiko Nakaya has installed one of her iconic fog sculptures, titled Cloud #07156, inside the Rotunda of the Bourse de Commerce in Paris. The work, on view until September 14, 2026, is part of the exhibition Clair-obscur, which explores chiaroscuro and its contemporary legacy. Visitors are invited to walk through the thick white water-vapor fog, appearing and disappearing within the space, which features a concrete cylinder designed by architect Tadao Ando. The piece uses high-pressure pumps and nozzles to produce tiny water droplets that mimic natural fog, a technique Nakaya has refined since her first fog sculpture at the 1970 Osaka Expo.
This installation matters because it continues Nakaya's pioneering practice of sculpting with natural phenomena, a legacy rooted in her 1960s involvement with the Experiments in Art and Technology (EAT) collective. By bringing fog—an ephemeral, unstable material—into the museum's architectural context, Nakaya challenges traditional notions of visibility and observation, creating what critic Anne-Marie Duguet calls an "anti-panopticon." The work also underscores the enduring relevance of environmental and experiential art, inviting audiences to move within the sculpture and reflect on perception, ecology, and the boundaries between art and nature.
