This panel's primary concern was to modulate light in two distinct ways with minimal user participation. To do this, the panel is comprised of a bundle of cylindrical. Fiber optic rods are positioned within the interstitial space between the tubes. When standing in front of the panel, one can look directly through the tubes and beyond. From an oblique angle, the depth of the tubes prevent light as well as the view from passing through. At this angle the fiber optics sandwiched between the tubes become highly visible, and in contrast to the open tubes, much brighter.
