Patent abstract
A reflective or light redirecting device has a base with an overlaying pattern or light redirector. The pattern can be selected from a collection of masks, templates, or reflective appliques. The device is arranged to reflect or redirect light, for example sunlight, in a beam that projects a corresponding design. A motor rotates the device and reorients its directional axis to reflect light toward a surface to circulate the design on a path on the surface.
