Bryan Clark is working on an interesting project: Background Channels. The idea is to create a Gnome service that allows you to connect to an RSS feed with background images, when a new image is available it is downloaded and installed as a desktop background. There is some code written already, but the project seems to need quite a bit more design and coding before completion.
It would be nice if this image feed parser service is generic enough so it can be used for other purposes, not only for desktop backgrounds. For example: splash screens, slide show screens savers, backgrounds for other applications, etc.
Also this image feed parser could work as an agregator, it could collect images from several feeds. You should be able to set how often you want your background swapped (not more than once a day for example), if more images are coming in then they should be queued up.
During the summer a nice image feed would be one with the latest crop circles ;-)
The project has a wiki page now, keep an eye on it.
