This example shows a geometric composition inspired by Sol LeWitt's wall drawings. It creates two circular masks overlaid on a grid of thin rectangles. A series of horizontal bars are clipped to a central white circle, while vertical bars outside that circle are shown through an inverse mask. The result is a crosshatched pattern that reverses direction at the boundary of the inner disk. The piece uses raw SVG manipulation via the DOM API, constructing elements with `createElementNS` and applying `mask` attributes to control visibility.
