Kites over a photo of an aspen tree. Darts over a photo of a saguaro cactus.
Every vertex belongs to one of seven distinct groups. ‘Queen’ groups are emphasized with an overlay blend.

#zentangle #mandala #art #PenroseTiling #geometry #math Creature Network Art exercise / pareidolia on a Penrose tiling template (kites and darts with arcs intersecting the points that define tile placement).

In a Penrose P2 tiling, every vertex belongs to one of seven distinct groups. Four of those groups are emphasized here that, to me, look like beetles, horseshoe crabs, and two different kinds of starfish, one of which is embellished for effect.
