I've just started playing with Tour Wrist (free), and am really enjoying the panoramic views from around the world. You can move around in the 3D panorama in "immersive mode" by moving your iPhone or iPad up or down, or on an axis. Or you can toggle it to "touch mode", so that you simply move around by dragging your finer on the screen. For example, I began with a gorgeous beach scene in immersive mode. As I held my iPad out and turned around my view changed as I moved. Or if I held my iPad above my head, I was looking at the sky.
