I thought I'd try something different as an exercise. I want to create a
chechered sphere.
Trying to make a sphere with a checkered pigment won't give nice results. So I
thought I'd try my hand a "image_map"ing. I created an image_map (see attached
checker.png) and created a sphere with an image_map like this:

sphere{
 0,1
 pigment {
      image_map {png "checker.png"}
      scale 0.2
  }
}

What I don't get is how to make the image map wrap the entire sphere nicely.
I'd be interested to hear how you pro's do this.
