A vertical Sol LeWitt reproduction renders 100 horizontal stripes, each 10 pixels tall, clipped by a circular mask centered on the screen. A second set of 100 vertical stripes, also 10 pixels wide, overlays the horizontal ones without masking. The piece uses plain SVG created via the Document Object Model (`document.createElementNS`), with a `<mask>` element and a white circle to define the visible circular region. The page fills the browser window, with stripes spaced 20 pixels apart, producing the grid-like optical effect characteristic of LeWitt’s wall drawings.
