A web page reproduces a Sol LeWitt wall drawing using SVG, where horizontal and vertical stripes are clipped by two circular masks to create overlapping geometric forms. The page builds the composition dynamically with JavaScript, creating a full-screen SVG and adding one hundred horizontal bands intersected by one hundred vertical bands. Each band, drawn as a thin rectangle, is masked so that horizontal stripes appear within one circle and vertical stripes within another, producing the characteristic minimal, grid-like pattern. The code uses the SVG `<mask>` element and `document.createElementNS` API to assemble the artwork entirely in the browser.
