Abstract wallpapers

The geometric style is a grid of quarter circles, triangles, dots and half squares, each tile picked at random from the seed. It takes after mid-century poster design and textile prints, and it changes character a lot with the palette.

Use a light base color for a printed-paper feel, or a dark one for a more graphic look. Higher resolutions give more tiles only on wider formats, so an ultrawide gets a longer pattern rather than bigger shapes.
