| 摘要 |
The invention relates to accessories for education and/or recreation, executed as a "kit of part" or not, comprising, on the one hand, one or more three-dimensional target objects and, or the other hand, several two-dimensional reproduction parts by means of which the three-dimensional objects can be represented. The three-dimensional target objects preferably comprise three-dimensional cube shapes and the two-dimensional reproduction parts preferably comprise flat diamond shaped pieces, and optionally triangular pieces, which can be positioned in a plane in such way that they form a two-dimensional image or representation of a target object consisting of one or more cube shapes. Preferably at least the mutually intersecting lateral sides of the three-dimensional cube shapes show a different colour or pattern, and the colours or pattern of the flat diamond shaped or triangular pieces correspond to the different colours or patterns of the lateral sides of the cube shapes.
