‘Blooms’ is a unique type of 3D-printed sculpture designed to animate when spun and lit by a strobe light (or captured by a video camera with a very fast shutter speed).
John Edmark explains:
What you are viewing in this video is a bloom spinning at 550 RPMs while being videotaped at 24 frames-per-second with a very fast shutter speed (1/4000 sec). The rotation speed is carefully synchronized to the camera’s frame rate so that one frame of video is captured every time the bloom turns ~137.5º—the golden angle. Each petal on the bloom is placed at a unique distance from the top-center of the form. If you follow what appears to be a single petal as it works its way out and down the bloom, what you are actually seeing is all the petals on the bloom in the order of their respective distances from the top-center.
