A combination of hexagons, squares and triangles that infinitely tiles the plane.
Due to its hexagonal nature, can't be tiled on a square grid regularly, so the snapping is offset.
First time you tile, place however you like, then align the blueprint in between 2 rows of tiles previously placed and freely fill in the gaps
