Golden Sunflower

Phyllotaxis: seeds sit at a constant turn. The golden angle packs them. A tenth of a degree away, they line up into spokes.

137.500°
0.008° from the golden turn

Still packed. Nudge it.

137.5° sits a hair from the golden turn. The head still looks like a sunflower. Press +0.1° or −0.1° and the spirals collapse into spokes.
