BLOOMS 2: STROBE ANIMATED SCULPTURES BY JOHN EDMARK

Friday, January 20, 2017

Blooms are 3-D printed sculptures designed to animate when spun under a strobe light. Unlike a 3-D zoetrope, which animates a sequence of small changes to objects, a bloom animates as a single self-contained sculpture. The bloom’s animation effect is achieved by progressive rotations of the golden ratio, phi (ϕ), the same ratio that nature employs to generate the spiral patterns we see in pine-cones and sunflowers. The rotational speed and strobe rate of the bloom are synchronized so that one flash occurs every time the bloom turns 137.5º (the angular version of phi).* Each bloom’s particular form and behavior is determined by a unique parametric seed I call a phi-nome (/fī nōm/). — John Edmark



* For this video, rather than using a strobe, the camera was set to a very short shutter speed in order to freeze individual frames of the spinning sculpture.
