A unique puzzle that will be appreciated by mathematicians and puzzle enthusiasts, it is also a desirable object in its own right. For those who want to understand the 'science bit', an explanatory DVD is included - apparently "All Five" refers to The Platonic Solids; five shapes that have fascinated human culture since prehistory but whose importance was first discussed by the ancient Greeks. There is lots more information on the DVD, but the important bit to understand is that each shape is a puzzle itself, each interlocking in different ways, and all five nest inside each other to form a single complex puzzle - very clever stuff! And pretty too, with the pyramid and icosahedron (largest puzzle) shapes made in a marquetry-style pattern from rubberwood and beech.
