This example reproduces a Sol LeWitt wall drawing using generative linework confined to circular masks. Horizontal and vertical striped rectangles are layered across the full canvas, with an SVG mask revealing only the central circular area for each orientation. The piece uses pure JavaScript and the SVG API, creating two masks and drawing one hundred striped rectangles of alternating orientation. The result is a minimalist, geometric composition that directly emulates LeWitt’s instructional art style.
