This piece reproduces a Sol LeWitt wall drawing using JavaScript and dynamically generated SVG. It renders a full-screen series of horizontal black bars, evenly spaced, which are then clipped by a mask containing a single white rectangle and a central black circle. The resulting composition shows the striped pattern visible only outside the circular cutout, creating an inverted hole of solid white space. The work uses the standard SVG `mask` element and procedural creation of `rect` nodes through the Document API.
