Sculpture looks animated when rotated

These 3-D printed sculptures, called blooms, are designed to animate when spun under a strobe light. The rotation speed is synchronized to the strobe so that one flash occurs every time the sculpture turns 137.5 degrees. 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.
