Abstract

A device for successively displaying a plurality of images includes a plurality N of overlying panels where N is at least 3. Each of the panels defines a longitudinal series of flexible slats and louvers between the slats, the slats being longitudinally longer than the louvers. Each of the slats of all underlying panels are interleaved longitudinally through the louvers of all overlying panels, the slats of each panel cooperatively defining one of the plurality of images. Each of the slats of an overlying panel is laterally narrower than the slats of all underlying panels. A knob is provided for moving in turn each of a subplurality N-1 of the plurality of panels a length at least equal to the length of a louver such that movement of a given panel in one longitudinal direction exposes the slats of an adjacently overlying panel and conceals the slats of the given panel underneath the slats of an underlying panel, and movement of the given panel in the opposite longitudinal direction exposes the slats of the given panel and conceals the slats of an adjacently overlying panel under the slats of the given panel.
