This generative art piece reproduces Sol LeWitt’s conceptual aesthetic by rendering 100 alternating horizontal and vertical stripes across the full browser viewport, with a circular mask applied to each set. The stripes are created as SVG `rect` elements, with horizontal bars masked by a white circle and vertical bars masked by a black circle, producing a layered checkerboard-like interaction. The code uses raw SVG manipulation via `createElementNS` and `setAttribute`, with no external libraries. The masks (`circle-mask` and `circle-mask-2`) define a central 200-pixel-radius zone, revealing or hiding stripes dynamically based on the window’s dimensions.
