School-kid patina I hear you cry? What is that? I brought the 28 double tori up for a summer-long tryout to the Maryland Science Center and 40,000 school kids were encouraged to put their hands all over the pieces. It didn't take any encouragement at all. Now this regular isogeny is as familiar to those little tykes as the phases of the moon.

A regular isogeny, homotopy, or smooth deformation of a double torus in linked form to and unlinked form. This piece is a theorem and proof, in fact, contains the germ of the proof for the classification of surfaces by handles and cross-caps.
