Hopefully you're already doing this, but remember to rotate the ball
rather than just translating it.

I am not quite sure what you mean. Surely the idea is that you can see
the holes? If you mean the holes aren't becoming transparent when the
rest of the ball is, the solution is to put the transparent pigment on
the difference rather than the sphere; instead of:
difference {
  object {
    Sphere
    pigment { Transparent }
  }
  object { Cylinder1 }
  object { Cylinder2 }
  object { Cylinder3 }
}

do this:

difference {
  object { Sphere }
  object { Cylinder1 }
  object { Cylinder2 }
  object { Cylinder3 }
  pigment { Transparent }
}

Not sure if this is what you want; please ignore me if I'm stating the
obvious. Otherwise, I hope that helped.
