Instead of piling on columns, the final tower used crisscrossing spiral beams forming spatial quadrilaterals, then pulled each node inward with tension cables — and anchored the top vertically to the ground to kill sway. Stability came from a web of opposing forces, not mass. The lesson: the lightest structures are often the ones that know how to pull as hard as they push.
