Christian (Insignia) posted a series of images to his Facebook profile last week detailing a few diagrams wherein a body could transition between triquetras and cateyes in a variety of really fascinating ways. After playing around with the idea for a little while and realizing it featured a geometric concept called a vesica piscis, I worked out where playing with cateyes and triquetras using the concept could take you. Ironically, the shapes are all axially, but not radially symmetric as Christian's diagrams came out.
