Abstract (en)
[origin: EP0063816A2] The puzzle consists of a plurality of three-dimensional bodies (1) which cannot be separated from one another, are movable relative to one another and can be accommodated inside one another, the inner surface of the outer three-dimensional body (1) being a spherical surface or being a surface provided with a spherical covering surface, and the outer surface of the inner three-dimensional body (1) which is adjacent to the outer three-dimensional body (1) being a spherical surface or being a surface which can be bounded by a sphere, symbols (3) also being present on the three-dimensional body (1) which can be displaced by their movement relative to one another. The spatial puzzle serves for developing patience and three-dimensional vision. <IMAGE>
