Bryant-Kusner Boys surface. Boy's surface is an immersion of the real projective plane in 3-dimensional space found by Werner Boy in 1901. It has no singularities (i.e., pinch-points), but it does self-intersect. This figure is based on the parametrization discovered by Rob Kusner and Robert Bryant.
