Renders algorithmic art entirely in the Worker from a seed, so every piece is reproducible: Truchet tiles, packed circles, golden-angle phyllotaxis, Mondrian subdivisions, L-system plants and random walkers are produced as crisp SVG; Perlin-noise flow fields, wave interference and Voronoi cells are rasterised to PNG with the in-house encoder. Eight curated palettes, a density control and stroke width shape the result; the preview shows the piece and the download is the SVG or PNG file. A share string in the info reproduces any piece exactly.
