This piece displays a black-and-white grid of horizontal and vertical stripes that intersect in a circular region at the center. The code constructs an SVG canvas sized to the browser window and uses two SVG masks to alternate visibility within the circle. One mask reveals the horizontal bands, while the other reveals the vertical bands, creating the illusion of a woven pattern. The piece is a direct reproduction of a Sol LeWitt drawing, generated through low-level SVG creation via the DOM API without any external visualization libraries.
