Numerical Flowers

This generalizes how seeds are distributed on plants such as sunflowers. Starting from the center, each successive seed is a fixed distance from the previous seed and is rotated from the line connecting the previous two seeds by a constant angle. Using the controls, you can explore how different angles, , produce varying patterns with seeds.
The angle is represented as a percentage of a full rotation, so 45 degrees would be 1/8. If you enter a number greater than one, you get the same result as you would with the fractional part of the number. Therefore, is the same as .
