A gobo is a small stencil used in lighting to shape or texture a beam of light. It’s usually made of steel or glass and features a cut-out or etched pattern. When placed in a holder or slot in front of a light, between the source and the lens, the light passes through the gobo and projects that pattern onto the stage or set. This allows designers to create textures like leaves, windows, or abstract designs without additional props. The other options describe different stage elements (a rotating platform, a top-down viewpoint, or a box-set wall configuration), but they don’t refer to the lighting pattern technique that a gobo provides.
