ABSTRACT:
A microelectronic-based timekeeping apparatus having several display means, such as liquid crystal displays, that change color to indicate the time-of-day, and user accessible switches for setting modes of operation, are mounted within an aluminum frame. Time-of-day is represented by the dynamically changing relationship among the several display means. Display means consist of light valves alone, or light valves in combination with a backlighting means. The apparatus is suitable for integration with a work of abstract art and may be free-standing or hung on a wall.
