4x6

Designer: Petar Zaharinov
Goal: Assemble the twenty-four elements (four types, six pieces each) into the interlocking structure shown in the picture.

Materials: Wood
Classification: Interlocking

Notes; The design was found while examining the possibilities of using interlocking puzzles in the field of industrial design and architecture. The goal was to find an interlocking structure, that is not too complex and difficult to produce. Furniture and houses were the main objects of interest. Probably the task was just the opposite of the one of puzzle design, but the result can be interesting even taken out of its practical application – as abstract structure.
