3 Eight-sided Polygons [Dotted Grid] V2

Processing sketch.
Four vertices of each polygon are placed on vertical and horizontal axes, and other four vertices in each quadrant of the composition. All vertices on axes overlap. There is 50% chance for quadrant vertices to overlap. Three polygons. One red, one green and one blue with 50 transparency.
1M variations.
