  If the cosine of the angle between the normal vector and the light
vector is negative it means that the normal vector is pointing away
from the light source. That is, the surface is pointing away from
the light source. It shouldn't thus be illuminated.
  I assume that if you remove that piece of code, all your surfaces
will be double-illuminated.
