If you use a Mac the program iphoto has a slideshow option. By clicking on the play button in the library or album view window, it will bring up the slideshow settings menu. Click the Automatic Ken Burns effect, then hit play. The slideshow should appear fullscreen, and you will be able to see the results of the Ken Burns effect( which basically pans, tilts, and zooms in/out) in random order for each picture in the slideshow.
