In ‘Extension’ an camera films the moving sculpture navigating its environment, this turns the sculpture into a piece of documenting apparatus - filming is integral in the making of the work and so the documentation isn’t separated from the working process. The fork lift extensions that the title is based on are put on fork lifts to carry larger things. Here the tool (the extensions) and the thing its carrying are one piece. The work isn't separated from the tool and the documentation isn't separated from the working process.
