The Fibonacci Ellipses collection shows arrangements of ellipses whose major axis (height) and major axis (width) are two consecutive Fibonacci numbers. The length of the large main axis of an ellipse becomes the length of the small main axis of the following ellipse. From the property of the Fibonacci numbers it follows that the major axis of the following ellipse is the sum of the major and minor semi-axes of the previous ellipse.
The Fibonacci Flower image uses the ellipses to bring to bloom the petals of a mythical and fabulous flower that vaguely resembles a lilac water lily. The petals are continuously rotated around the center by the golden angle and touch the innermost ellipse (a circle). Similarly, many plants in nature do this to minimize shading of their leaves and maximize sunlight.
