The Flexi-Cubus is a mechanical model, an octasphere puzzle in the form of a steampunk skeleton cube made out of eight joint-connected spheres. This flexible connection allows the spheres to move and roll over one another creating different geometrical shapes.
Each sphere is a mini-mechanism comprising six segments connected with a hinged joint.  The geometrical model takes the shapes of a rectangle and a 3D cube transforming by bending the joints from one to the other and back as many times as you want.
The Flexi-Cubus is designed as a means to improve your attention and focus on a task you are working on. It will help you to relieve anxiety and stress, and direct your thoughts and feelings in a positive way.
