[math-fun] Saddle-shaped minimal surface bounding a non-planar hexagon

Do any of you know of any pictures (hand-drawn or computer-generated) of the saddle-shaped surface you get when you make a non-planar hexagonal frame consisting of all the edges of a cube that avoid two antipodal vertices an dip it in a soap film solution? This is not to be confused with the surface you get when you dip a non-planar octagonal frame consisting of the edges in a Hamiltonian cycle on the cube. I spent about five minutes searching images.google.com and didn't find what I'm looking for, and would appreciate help from any of you who may know about where such things can be found! Thanks, Jim Propp
