Shift key click flag (turbo). Move with mouse for 3D (parallax). Adjust colors to highlight different spiral patterns. Like pineapples & pinecones, spiral counts are Fibonacci numbers. (With the mouse you can smash spirals against the sides, if so inclined to flatten pineapple, or else gently rotate). See a diversity of spirals arising from turning the golden angle, 137.5077... degrees, the angular version of Phi, the golden ratio. The color slider changes the number of colored spirals visible.
The 3D effect is by parallax moving outer clones more. The colors show different spiral patterns, some clockwise, others counterclockwise. The spiral counts are always Fibonacci numbers, as in a pinecone or pineapple (or in 2D, sunflowers, daisies and countless others). The sprite starts from the center and turns the golden angle (137.50776405...degrees). This golden angle turn is the best way to fill space, and causes the number of clockwise and counterclockwise spirals to be Fibonacci numbers (such as 5, 8, 13, 21, 34, 55, 89, 144....), but hard to count in this one. Sunflowers, daisies and many other flowers have florets that form these type of spiral patterns.
