This visualization reproduces a Sol LeWitt-style geometric composition on a full-screen SVG canvas. It shows a grid of thin horizontal and vertical bars intersecting around a central circular void, creating a cross-shaped negative space. The piece uses two SVG masks to selectively reveal either the horizontal or vertical rectangles. One mask shows a white circle on a black background, while the other is inverted; JavaScript loops generate 100 rectangles in each orientation, each assigned one of the masks to achieve the layered effect.
