Reglets (R1-R8) joined side by side and sliding in the longitudinal direction are each provided respectively with successive transversal tapes (A1, B1, C1) cut out from an image and fixed by means of strips (L) offset under the following tapes (A2), the different tapes located at a same level are overlapping each other so that by sliding any reglet in a direction opposite to the strips, a new image appears which is composed by the tapes carried by said reglet.
