Curves and Immersions

 The Thumb

This animation shows the steps to go from a disk (on the sphere) to the curve that we recognize as bounding a punctured torus (with a degree number added to each region). Since, on the sphere, this curve is equivalent to the Milnor curve we have shown that this curve bounds a disk in two ways as well as the torus.
