I think of it as an upside-down T, where the camera/body/vehicle stays at the plane of the crossbar. You move the trunk forward and the crossbar tilts forward. This brings the nose of the plane (not airplane, but it is still applicable) down, along with your line of sight. Pull back and the nose comes up, raising your sight.
That head explanation was great, spdiscus.
