Abstract:
A display and method for depicting the passage of time by selectively and progressively filling predetermined areas, each area representing hours, minutes, seconds and tenths of seconds respectively. The areas may be of any shape or combination of shapes. The portion of the area that is filled represents that portion of an hour, minute, second or tenth of second that has passed. The areas may be normally dark in which case filling illuminates the area. Areas may be normally light in which case filling darkens the area. The areas may be any visually perceptible medium capable of changing light intensity or color including discharge tubes, light emitting diodes, liquid crystal displays, fiber optic bundles, or hologram images. The areas may be arranged in unconventional and discontinuous patterns and incorporated into a wide variety of objects.
