Phyllotactic spirals form a distinctive class of patterns in nature, in general, the arrangement of leaves on a plant stem or the pattern of seeds on the face of a sunflower. This patterning can be generated via a mathematic algorithm.

I imagined these patterns as fireworks and sought to create images of Phyllotactic Firework displays. Initially, the phyllotactic spirals, or blossoms, are distributed as tiles over the picture plane in a regular grid but only 40% of the tiles are drawn. I add a bit of displacement to the center of each tile to conceal the regular placement of each tile in the grid.

The phyllo seeds (round dots) vary in size and "tightness," for each blossom drawn. I add randomness to the phyllo spiral by varying the dot intervals a bit, as well as give a random range to the dot size.

The background color is an RGB color for a night sky. Color varies over phyllo-seed spiral. From the center seed, assigned a random starting color on the color wheel, incrementally changing to another random color assigned to the last seed.

I hope you enjoy my salute to Independence Day, 2023.
