![]() The pin screen provided by the present invention includes an apertured plate supported in a substantially horizontal fixed position by a supporting table, platform or the like. Light rays impinging upon the pin heads positioned at varying attitudes relative to the apertured plate, or upon the moving pin heads, provide the appearance of visually animated action and dynamically changing displays. The pins may also be moved such that the pin heads are intermediate the lower apertured plate and the upper transparent sheet. The pins are vertically movable relative to the horizontal plate between a lower position in which the bottom of the pin heads abut against the upper surface of the plate, and an upper position in which the top of the pin heads abut against the lower surface of a transparent sheet of material spaced at a predetermined distance above the apertured plate. The heads of the pins are larger than the diameters of the apertures to assure that the pins do not fall through the apertures. The plate is supported in a substantially horizontally fixed position, and each of the apertures defined therein are adapted to receive a pin in a substantially vertical orientation.
