Abstract: A plurality of light sources are arranged with a light-guide structure such that light emitted by the sources propagates longitudinally through the light-guide structure. The light-guide structure scatters and/or redirects the emitted light and outputs the scattered and/or redirected light laterally. A controller is configured to dynamically correlate the light emitted from the plurality of light sources and to dynamically tune intensity of the light emitted from the plurality of light sources. The result is a dynamic light effect that appears to the observer as moving light.
