Artist Sarah Meyohas has unveiled her first public art installation, "Truth Arrives in Slanted Beams" (2025), for the 2025 edition of Desert X in California's Coachella Valley. The monumental curved structure uses no electricity; instead, precisely milled mirrored discs reflect sunlight onto a white wall to form legible patterns and messages through the optical phenomenon of caustics. The work was created in collaboration with the Swiss company Rayform, which specializes in calculating caustic light patterns, pushing their technology to its largest scale yet.
This installation marks a significant departure for Meyohas, known for her high-tech, cryptocurrency-based projects like BitchCoin, and demonstrates the growing intersection of cutting-edge optical engineering and public art. By harnessing natural light to create dynamic, text-based imagery without projections or digital screens, the work challenges assumptions about technology-driven art and expands the possibilities for site-specific, environmentally responsive installations. It also highlights Desert X's role in commissioning ambitious, experimental works that engage with the desert landscape.
