Cool Graphs on Spheres

A little while ago I published a post called Function Graphs in the Real Projective Plane. I thought the functions traced on the sphere had a pretty cool look like the image below. So…  You can go here and find three spheres one below the other which can be  rotated any way that you want with a computer mouse.  This is done with a CDF file (computable document file) and requires a CDF plug-in which can be found here. The yellow dot at the intersection of the green and red lines (the axes) is the origin.  Enjoy.

I am a sixty-five year old math instructor at Southern Oregon University. I taught at the College of the Siskiyous in Weed California for twenty-six years. Prior to that I worked as a computer programmer, carpenter and in various other jobs. I graduated from Rice University in 1967 and have a MS in Operations Research from Stanford. In the past I have hand-built a stone house and taken long solo bicycle tours. Now I ride my mountain bike and play golf for recreation.
