The analogy here is that you're looking through a gun-sight or an eyepiece (rather than a visor), and your head movement is moving in unison with the gun or turret itself. You can do this with a regular game object (for example, Quad + texture image), but this chapter is about UI. So, let's use our canvas, as follows:
