Pendulum is a large-scale performance installation created by Australian choreographer Lucy Guerin and percussive artist Matthias Schack-Arnott. The work presents an artistic domain that integrates dance, sound and installation through 39 specially designed interactive pendulums. Each bronze pendulum contains a sensor, speaker and light source that translates the dancers’ physical movements into real-time, multi-layered audio and visual feedback. During the performance, the dancers use modern dance techniques to engage in a dialogue with the weight and rhythm of each pendulum. The pendulum's rhythmic oscillation measures the passage of time, and its trajectory outlines the irreversible laws of physics, while the dancers' intervention embodies humanity's struggle and adaptation within time's eternal flow. The work reveals - between the tension of mechanical laws and the will of life - the fragility of human existence and resilience of the human spirit.
