A web of decagons woven with pentagons. The holes are irregular hexagons made from two overlapping pentagons. Perhaps I should have made the green pentagons pink but sometimes it's hard to say no to green. The pattern derived from the Degagon Zig-Zag: using pentagons instead of triangles and filling in a bunch more pentagons. The rotation symmetry of the purple pentagons is a remnant of the zig-zag construction.
