An illumination system configured to produce color movement along the length of an optical fiber. The system can include a light-diffusing optical fiber (12) having a first input end and a second input end, a glass core (20), a cladding (40) surrounding the glass core, and an outer surface. Nano-sized structures (32) are situated within the glass core or at the core-cladding boundary in order to scatter light. A first light source (150a) is optically coupled to the first input end, and a second light source (150b) is optically coupled to the second input end. A color variation forms within the optical fiber at the junction of the light emitted from each end of the fiber, and adjusting the intensity of light emitted from one or more of the first light source and the second light source causes the location of the color variation to move along the length of the optical fiber. |
