Abstract
A visual display element, which may be used singly or as part of a large bank or like and similar elements, each element comprising an encasement, a slotted plate, and an actuating assembly. The actuating assembly comprises a planar face with a colored pattern of lines thereon and is situated immediately behind and parallel to the slotted plate. When viewed from the front, the planar face and adjacent slotted plate, the slots of said plate comprising highly reflective surfaces, which collectively appear as a solid color. Selective relative movement between the planar face and the slotted plate causes the visually perceived color to change from one color to a contrasting color and thereafter back to the original color.
