It consists of limited number of pieces, with a total of six pieces which correspond to the symmetrical half of the planes which, cut orthogonally, correspond to the formation of a solid or hollow, regular hexahedral or spherical geometric figure, which are assembled together by means of simple arrangements of notches or assembly by means of simple flanges tangential to the ends of said pieces, and which may be formed by uniformly closed or concentrically recessed planes such that, inside the hollow figures, it is possible to accommodate other, similar geometrical members or members proportional to these figures, progressively reduced in size, or solid or hollow cores in accordance with the principal figure, or vice versa, formed by a single piece or a number of pieces in different colours. The object applies especially to toys, and to adornment, advertising or teaching elements. <IMAGE>
