A generative drawing creates a randomized geometric composition inspired by Sol LeWitt's wall drawings. The piece shows layered bands of rectangles meeting at the canvas edges, with a central diamond-like void formed by four triangular masks. Using plain JavaScript and the SVG DOM API, the code constructs masks and randomly sizes and positions horizontal and vertical rectangles to create a structured, grid-like pattern. Each render produces a unique variation based on the random offset and per-rectangle dimensions.
