Seeing Spheres

Seeing Spheres is a public artwork that turns shared space into a moment of reflection and connection. Five polished, hydroformed steel spheres—each about 15.5 ft (4.7 m) tall and 15.5 ft (4.7 m) in diameter—with inward-facing mirrors framed by LEDs create shifting, tunnel-like views. CIG delivered engineering, materials, production, pre-assembly, and installation support in San Francisco, using hydroforming—immersing faceted steel pieces in high-pressure water—to form perfectly round, smooth shapes.
