The original 8mm film was shot when Glenn was studying his art degree in 1975. He rediscovered the reels, nearly destroyed by mould in a box under the stairs, and had them digitally converted. He then edited the resulting, “…damaged and richly atmospheric…” conversion, adding audio atmosphere and sound effects, as the original footage was silent. At the time he was fascinated by the “…ubiquitous and invisible transference of electronic information…”. Like most of humanity he took much of the technology that impacts our lives so profoundly (television, radio and now WIFI etc) for granted. This filmed piece was his attempt at “… intercepting the incalculable amount of information that’s ‘hidden’ in the invisible”. In itself the act of casting the screen while the transmitted images flickered beneath the dripping plaster was, for him, not only a visually exciting experience but also a hazardous one.
