Cubic Sphere

Again ,I'm exploring cubic symmetry here, only this time I've pre-formed the 6 round disks so that their concave shape matches and fits perfectly the surface of a sphere. I'm not a numbers guy per se,but I have a highly developed sense of spatial relationship and can intuitively grasp the correspondent scale and size relationships required to make these parts fit...There are formulas that can be utilized with computer programs to construct and render many complex geometrical shapes,which are a great source of inspiration to me. I communicate sporadically with some of these math wis kids and often make in model form their virtual explorations...
I also gain much inspiration from the Wolfram web sites.
