An unlikely system comes into operation during the night shift. Structures emerge, transform, and disappear systematically, following chain-like trajectories triggered by a solitary agent. In this spectacle of contemporary juggling, the perception of time and materiality is distorted by routine, causing ordinary objects, such as balls and tubes, to be reconfigured in a continuous mechanical process.
