Wally: Best Automatic Wallpaper Changer Application I've Seen

We wrote about different automatic wallpaper changer applications either for Windows, Linux and / or Mac OSX but Wally is special. Wally is a Qt4 wallpaper changer, using multiple sources like files, folders, FTP remote folders, Flickr, Yahoo!, Panoramio, Pikeo, Ipernity, Photobucket, Buzznet, Picasa and Smugmug images. Not only that, but it also works on Windows, Linux and Mac OSX. Ubuntu users will be glad to know that it even comes with pre-build .deb packages for both 32 and 64bit versions (download link at the end of the post).
