Rae Douglass invented the means to produce a field of multi-colored light that appears to emanate from the center of a hollow tube or solid rod. The key to this invention is the alignment of the diffraction surface into a tubular structure. The light field appears to vary in color as a person views it from different angles and positions. . Rae has adapted this technique for use in light fixtures, sculpture and environmental signage. Rae has also devised a means to wrap flexible suspension cables with the surface to create monumental color displays. The diffraction surface is illuminated with a remote white light source that can also be the sun.
