Triply Punctured Torus

The sculpted shape is topologically equivalent to a torus with three punctures. The images below, created in Mathematica using the late Al Gray's parametrization of a Costa surface and simply morphing between that and a torus (an idea of Dan Schwalbe), show one can transform a triply punctured torus to a Costa surface.
