Watch 3d Printed Fibonacci Sequence Sculptures That Come To Life When They Start Spinning Under The Strobe Light
John Edmark, is an inventor, designer and artist who teaches design at Stanford University in Palo Alto, CA. Edmark created a series of 3-D “Fibonacci zoetrope sculptures” that are designed to animate when spun under a strobe light. The placement of the appendages is determined by the same method nature uses in pinecones and sunflowers.

Fibonacci sequences appear in biological settings, in two consecutive Fibonacci numbers, such as branching in trees, arrangement of leaves on a stem, the fruitlets of a pineapple, the flowering of artichoke, an uncurling fern and the arrangement of a pine cone, and the family tree of honeybees.

In this video you will see 3-d printed sculptures designed to come to life when spinning under a strobe light. The placement of the pieces of the sculpture follows the same points used in sunflowers and pinecones. The rotation is done so the sculpture spins exactly 137.5º for every flash of light. 137.5º is known as the golden angle. If you count the spirals on any of the sculptures in this video they will all match up perfectly with Fibonacci numbers.

Each petal on the sculpture is placed at a unique distance from the top-center of the form. If you follow what appears to be a single petal as it works its way out and down the sculpture, what you are actually seeing is all the petals on the sculpture in the order of their respective distances from the top-center.

While Edmark’s spinning sculptures create the illusion of the objects moving and morphing, the objects themselves are actually rigid forms and do not change in shape. This is a representation of what Edmark is referring to in his statement above when he mentions “the tenuous relationship between facts and perception.”
