The Curvish structure of the 8 has a lot away of the stitching of a Baseball or the lines on a Tennisball. In mathematics this curve falls roughly in the section of "Constant Curvature Curves" one can find a lot of information on this curve on the website of professor Palais et al and their program 3D-XplorMath that can be downloade for free at The image below is made with this program and there is even the possibility to view it in 3D if you have a pair anaglyph glasses.
