Normals never change the actual shape of the object, only the aspect of the surface.
If you want your checker pattern to change the shape of the sphere, you need to 
use an isosurface.

For that, you need to use layered pattern. Add 3 gradients pattern, one aligned 
along each axis, with a color_map like: color_map{[0.01 rgb 0][0.01 rgbt 1]}
