This interactive reproduction of Sol LeWitt’s geometric wall drawing uses the SVG JavaScript API to generate a grid of 48 vertical and horizontal lines. The piece shows a black square lattice, where each line passes through a circular mask, revealing alternating line directions inside and outside the ring. The code directly creates SVG elements, applying two different masks (`circle-mask` and `circle-mask2`) to alternate which lines are visible in the central disc. It runs in the browser, filling the viewport, and is planned for animation.
