This is a modification of the well-known tessellation of the plane with squares and regular octagons.
Two of the heptagrams are centered in the middle, while the other fourteen are smaller, and form a ring around the two in the center.
The ten pentagrams meet at a common vertex in the center.
The fourteen heptagrams, also known as {7/3} star heptagons, meet at a common vertex in the center of the whole diagram. I did the math using Geometer’s Sketchpad, and then colored the result using MS-Paint.
