Weaver

A loom you can see through. Set how many warp and weft threads you want and pick the structure — plain, twill, satin, basket, or a 2/2 tartan — then build the colour sequence for each direction and choose how it repeats: straight, mirrored, or turned back on itself at a point. The randomiser works from colour theory rather than chance, so an analogous or triadic palette comes out as cloth rather than noise, and the pattern downloads as a high-resolution PNG.
