‘Over-lighting exceeds capacity for assimilation in a 1970s video camera and images are ‘burnt’ into the surface of its tube. Here a unique property is discovered where both the passage of time and trace of that continuum are registered as one. A section of the original tape version records the image of the artist with a camera (via a mirror) panning, by stages, across the screen. Before movement the lens is covered and re-exposed after the change, and each time the image appears to be inscribed onto the screen. In the interactive installation a camera registers the live passage of time through a translucent polaroid shutter. Periodically the shutter lifts – triggered by the participants’ movements – and images are fixed and inscribed.’
