Country: UK, London

Duration: 0'55

Type: 2 screen installation-based video, silent

Material: Colour 16mm film, Found sign, Colour-sensing intervention tool (Q-Editor)

Date of Creation: March, 2024



This work is a 2-screen video. Using a colour-sensing intervention tool (Q-Editor), and a found sign around the London Underground, it was shot automatically in the underground corridors.

Left screen, when it detects a green colour (‘Go’ sign) being blocked, it triggers the 16mm camera to switch on; the crowd seems to be drawn to the sign; Right screen, when it detects a red colour (‘Stop’ sign), it triggers the 16mm camera to switch on; the crowd seems to be repelled by the sign; The film was paused after a warning by the metro manager. 

In the frame of an external strategic intervention, the crowd was re-trained automatically in a two-screen video.
