These mesmerising 3D-printed zoetrope sculptures by John Edmark appear static when viewed by the naked eye but when a strobe light flickers above them and the sculptures begin to spin they suddenly come to life. John explains:
These are 3-D printed sculptures 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. The rotation speed is synchronized to the strobe so that one flash occurs every time the sculpture turns 137.5º—the golden angle. If you count the number of spirals on any of these sculptures you will find that they are always Fibonacci numbers.
For this video, rather than using a strobe, the camera was set to a very short shutter speed (1/4000 sec) in order to freeze the spinning sculpture.
If you are lucky enough to have a 3D printer you can learn how to do this yourself over at Instructables.
