Slightly arched as a cambered wing of an airplane or the angle of a tire.

This is what deterministic mathematics looks like when number theory is allowed to organize itself geometrically. Every integer occupies its unique position on a Vogel spiral defined by the golden angle, while every frame independently recomputes the primality of every point using deterministic 6k±1 trial division to sqrt(n), performing up to one million live primality evaluations per frame. Primes emerge as incandescent ember-to-ivory structures while composites collapse into violet background noise, revealing that the striking phyllotactic spiral families are not imposed by the renderer but arise naturally from the irrational golden-angle spacing itself. The visualization is therefore simultaneously a real-time computational verification of primality and a demonstration that simple deterministic arithmetic, coupled with optimal geometric packing, produces the remarkably ordered structures observed throughout phyllotaxis and related natural systems.
