Interesting question. They’re design elements so to speak. They are the main component in solving the visual problem of providing a pleasing way to display a tv. Our solution was to include the tv as part of a large sculptural pattern of almost black (darkly stained vertical grained oak) boxes. As a counter point their rhythm across the wall is unexpectedly broken by the insertion of another box - the flat screen tv. The light coming from the boxes adds visual interest and mimics the light coming from the tv. All this is anchored by a low long shelf; floating off the floor with light also glowing from below. - Thanks for the question- Stan
