Erik Zachte to the rescue! He has just created an animated version of his main page gallery:
http://stats.wikimedia.org/wikimedia/gallery/SlideShowWikipedia.htm
He suggests downloading the files for offline presentations:
http://stats.wikimedia.org/wikimedia/gallery/GalleryWikipedia.zip (111 MB)
The delay between pages can be tweaked
var msec_next_slide=7000 ; var msec_pause_between_slides=1000 ;
Feel free to add this to tenwiki in the appropriate place.
