A transformation of designer Vaclav Obsivac's Diagra puzzle as part of his new HoWeDia project, this puzzle consists of eight wooden cubes, labelled A-H for easy identification. (Each puzzle is unique, so coloring may vary.) Multiple goals with different levels of difficulty are included, using four, six, or eight pieces based on the challenge at hand.

Each cube is 23 mm.  The completed version comes fits into a 60 mm wooden box.
