A CCTV camera displays the movement of a striking clock’s pendulum, through three television monitors in real time. On the monitors that are placed in three different directions, the motion of the same pendulum is shown from three different angles. This work manifests the circular relationship between image and reality within the operation of a closed-circuit TV. Also, by showing the clock’s movement this way, the work visu¬ally embodies the abstract flows of time. Swiss Clock therefore expresses Nam June Paik’s interest in “non-linear time.”
