Boy’s surface has 3-fold symmetry with an axis of discrete rotational symmetry: any 120° turn about this axis will leave the surface looking exactly the same. The Boy’s surface can be cut into three mutually congruent pieces. It has no singularities, but it does self-intersect. The idea was to parameterize the surface in order to manipulate the size/position of the wings and their intersections according to programmatic needs.
