    Abstract: A skeletal structure appropriate for the shell of very large very strong “skyscraping” life-spaces. Formed by pulling the center of a planar all-connect graph or mandala into cone, the very high symmetry of the resulting structure creates a shell of great beauty and strength. Large towers of square, hexagonal, or star-shaped, etc. cross-section can be created by dropping verticals from the planes of intersections in the grid-work of the shell.
