# Knot Complements

Using the menu in the upper right, you may select the knot you wish to draw. The program will then compute an embedding of this knot into the 3-sphere (by drawing the appropriate $(p,q)$ curve on a Clifford torus), compute a regular $\epsilon$-neighborhood of this curve with respect to the spherical metric, and parameterize the boundary torus of this neighborhood to draw under stereographic projection.
