This is about plant structure, called Phyllotaxis. The model represents leaves branching out from a stem, at successive stages that are rotated about the stem by 137.52…° between stages, a close approximation to the division of the circumference of a circle by 𝜑, the “Golden angle.” Scenes shows some aspects of the construction in vZome.
