An Arrangement of Squares Based on an Arrangement of Not Quite Regular Pentagons

more fun with online graph paper art

Rows of squares sometimes overlap, but columns of squares do not.

And now, a little bit more … and the key.

The squares mark the complete vertices of the graph formed by the packed pentagons, with blue for the 3-vertex points of intersection, and red for the 4-vertex points. All of the pentagons are similar, except for vertical reflection.
