To view these movies, download a QuickTime player, then slowly move the mouse across the picture while holding down the left button.
Once you have panned through the image (i.e., the entire movie has been tranferred), you can save the movie on your local disk by pressing the right mouse button and selecting "Save As QuickTime Movie..." from the pop-up menu. When you double-click the local file, it opens in the QuickTime Player, where you can select "Full Screen" in the "Movie" pull down menu to explore the panorama at large size.
