How can I change the flyover view angle in Apple maps?

Most of the gestures used in Apple's iOS 6 Maps application are pretty intuitive, but the 3D Flyover mode is a whole new mapping experience for iPhone 5 users. Of course you can pinch to zoom and turn your fingers on the screen to change direction in Flyover.

Some readers have asked how to change the view angle. This can be achieved by sliding two fingers up or down from the center of the screen. Sliding all the way up will show a view looking more towards the horizon. Sliding two fingers down brings the view closer to overhead, and will revert to an overhead view and exit Flyover mode if you drag down far enough.
