French interdisciplinary artist Julien Salaud creates mesmerizing installations for his “Stellar Caves” series, which he has shown in museums worldwide. The glowing grottos take inspiration from both constellations and ancient cave paintings. Salaud coats thread in ultraviolet paint and strings it throughout the room as if drawing directly on the walls. When lit with ultraviolet light, the room glows with a faint, blue hue that makes viewers feel like they’re traversing a night sky illuminated by stars. Salaud’s most recent piece, “Stellar Cave IV,” was recently on view at the Herzliya Museum near Tel Aviv.
