Juggling Motion
8 x 15 x 15 cm
3D printed nylon plastic
These two sculptures are "chronophotographs" (i.e. multiple exposure photographs): illustrations of paths through time with snapshots taken at regular time intervals. Three objects are juggled as the juggler walks forward at a constant speed. In one sculpture the objects are balls, in the other they are clubs. In both cases, the objects are being juggled in the three object cascade. The paths of the objects form the standard three strand braid. A 3D printed braid would fall apart into the strands, so in addition to the strands we also add the paths of the hands of the juggler.
