Abstract
A rotor presents bright and dark sides of a flat disk to a viewer. When the bright side is presented this side plus a stationary panel form a bright viewing area. When the dark side is presented the panel is occluded. The edges of the panel and of the disk in ON position define an aperture for light emission from an optic fibre end.
