Extrinsic Vertices Lattice

The first image below is one more from my Extrinsic Vertices project. The Extrinsic Vertices diagrams are an effort to create biomorphism through geometry. Sometimes the lattice of vertices is more interesting than the tiling it's based on. This diagram is from a radially symmetrical tiling based on a pentagon, an isosceles triangle, a square, a rectangle, and an isosceles trapezoid. The triangle subdivides a pentagon, but not the pentagon of the tiling. The lattice may reflect the 54, 72, 90, and 108 degree angles of the tiles.


Here's another:
