Suncatcher

A suncatcher or light catcher is a small, reflectve glass or mother of pearl piece that is hung indoors, so that it "catches the light" from a nearby source, usually hung at windows.

The Southwestern American Indians first began making suncatchers and they are now still popular in that region

Suncatchers may be mass-manufactured, or they may be created by hand, and can be of varying simplicity of design from an arts and crafts project to a professionally handmade glass sculpture.

Some designs are simple and abstract with perhaps some mobile-like chained elements, while more complex designs often evoke plants or animals.

A suncatcher is something like the optical equivalent of a wind chime, and indeed many designs combine the two.
