The word 'moiré' refers to visual interference patterns, which are created when two or more layers of simple dot, line, or grid structures overlap, producing an additional pattern on top of the original layers. Moiré patterns are often an undesired artefact of images produced by various digital imaging techniques, for example when scanning a halftone image, and is often an unwanted side-effect in printing processes.

The term originates from moire (or moiré in its French form), a type of textile characterised by a rippled or 'watered' appearance. In images, when two grids or series of parallel lines are overlaid at an angle, a similar effect is generated. The nonlinear interaction of the optical patterns of lines creates a visible pattern of roughly parallel dark and light bands, the moiré pattern, superimposed on the lines.

In a number of recent drawings from the series Rupture, I have generated moiré patterns through the layering of systematically produced lines. Generally speaking, instances of such visual disruption to images are generated unintentionally through the mechanical or digital processing of an image. As with all drawings rendered by hand, however, my drawings contain random deviations from a mechanically produced constant. Much of my recent work and research has similarly been characterised by such a dichotomy – the tension between the systematic and the uncontrollable, in both aesthetic and process terms, and references to the relationship between the mass-produced image and the unique object.
