Art work formed as colored translucent lines and areas on a design pane is illuminated to provide a changing display as a passageway panel between the design pane and a source of light rotates with the design pane to cause liquid in the passageway panel to flow from a passageway that is between the art work and the source of light to another passageway in the passageway panel where it does not block light from the art work. The art work may be illuminated progressively in any direction and at different speeds and locations by properly positioning the passageways. In the alternative, the liquid may flow from the passageway behind the art work to a separate movable container that is raised by a motor above the passageway and then lowered beneath the passageway while the design pane and passageway panel remain stationary.
