Unlike a 3D zoetrope, which animates a sequence of small changes in objects, a bloom animates as a single, self-contained sculpture. The animation effect of the flower is achieved by progressive rotations of the golden ratio, phi (ϕ), the same ratio that nature uses to generate the spiral patterns we see in pine cones and sunflowers. The rotational speed and frequency of the flower’s strobe light are synchronized so that a flash is produced each time the flower rotates 137.5° (the angular version of phi). The particular shape and behavior of each bloom is determined by a unique parametric seed that I call phi-nomial.
