Phyllotaxis
Interactions
- drag sideways across the flower head: turn the divergence angle by hand and watch the next seeds obey it
- click a seed: the two spirals through it are inked in, with their counts
- click the bud at the centre: the seeds fall and the head regrows from a bud
- click the bee: it flies off and lands on another floret
- move the pointer: wind for the petals and the leaves
