Abstract

In a multiple message panel with prisms having four or more sides adjacent to each other, during the rotation of such prisms a part of them, for example all those alternately placed (odd positions), is moved away from the panel surface, then these prisms are rotated together with the non-displaced ones and finally the first prisms are re-approached and aligned to the others, until the original panel surface is recomposed with a new message. In a preferred embodiment, the prisms that are moved away and re-approached have a cross section dimensionally lower than that of the prims which are rotated only.
