Optical (2007) by Stuart Haygarth.  The Optical chandelier is created from over 4500 prescription spectacle lenses. The lenses are hung on monofilament line which hang from a platform. The lenses form a spherical shape which imitates a disco mirror ball but rather than the light being reflected, the light is refracted through the many layers of glass lenses. A magical explosion of light is created. The light is illuminated by a clear 100w incandescent bulb.
