ThetaWall is a freeware program which turns your boring old Windows wallpaper desktop into a groovy slideshow using your photos. Just point the prog towards a sub-directory of images and it will update the desktop image every 5 minutes (or on demand with a double click).

It likes memory (runs in 20MB of RAM, plus whatever it needs for the images) so watch out if you’ve got large images to display. On the plus side it’ll cope with multiple monitors and also features a screensaver option, which is cool. www.info-svc.com
