For "Perpetual Response to Sound and Light (at the Locker Plant)" a searchlight was directed towards the glass facade of the studio building facing the train tracks. Microphones were transmitting the sound of the trains approaching from the desert and translating it into the light in order to create a pulsing light effect. Each time a train was approaching, the building was filled up with light.
