The ceiling resides in silence. Light, sound, and electricity live within it. It is a silent, service-oriented structure, a highway of energy flow between objects within the space. It is both overshadowed agency and a passage, supporting the hidden mechanisms of daily life. The film is shot using the Data Copilot film-device. King’s Cross (N1C 4XX) standard domestic electricity estimates (2015-2023) [from Department for Energy Security and Net Zero, UK Goverment] are collected to randomly send signals to the device, allowing the Bolex camera to autonomously alter its shooting speed and timeline direction, deconstructing the traditional concept of camera frame rates and linear one-way filming. Within the relationship of the filming machine’s autonomous conversation with the ceiling structure, send self becomes the meaning of it produce-calling for recognition and contact between subjects, transcending the subjective experience of a single subject. It hopes to release the electricity moving inside the ceiling from its quiet, passive, and service-bound role. —Hu Didi
