But which polygons would go nicely with each other?
Triangles, squares and hexagons (all of which you already have) are the only regular ones that would tessellate. Others, like octagons, don't tessellate but do still fit to make a pattern.
I think it'd be more interesting if you included some shapes that don't tessellate (at the moment they all do), because then people could investigate which ones do.
