ABSTRACT:
A 3-dimensional assembly is constructed from three 2-dimensional pieces. Each piece is formed with two slots such that the pieces are operatively identical and are interchangeable, and such that the pieces may be formed into a structure without bending of the pieces, and such that the pieces do not all share a common line of intersection. The resulting 3-dimensional structure may be used as a toy, puzzle, ornament, engineering structure, etc.
