These 3-D printed sculptures are designed to animate when spun under a strobe light. Called “Blooms”, this video films them with a short shutter speed.
Designer John Edmark teaches design at Stanford University. He comments on the video:
“These 3-D printed sculptures, called blooms, are designed to animate when spun under a strobe light. The placement of the appendages is determined by the same method nature uses in pine cones 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.”
