Roto-Sphere, a site-specific kinetic sculpture installed in the rotunda at the New York Hall of Science. Suspended above the visitors' heads, a large steel ring with two smaller inner aluminum "Roto-Rings" on a vertical cable, slowly rotates. As the outer steel ring rotates, "Roto-Rings" travel down the cable, spinning one on top of the other, gaining momentum until joining together to create the illusion of a solid sphere.
