Abstract
A panel with an optically transmissive portion includes a group of holes drilled from one surface to another surface and filled with an optically transmissive material. The group of holes forms a pattern. The holes on a first surface form a smooth and continuous appearance to the naked eye. The holes on the other, second surface are sized so that a light source directed to the second surface illuminates the pattern to be visible to a viewer viewing the first surface. The panel may form a portion of a housing that houses the light source.
