I love the great photos on Bing and I’ve been using the Bing photos wallpaper, set up as a slide show, so my background changes every 15 minutes to a new photo.  Very cool! 

Now the story gets even better.  I just learned of a dynamic wallpaper for Bing photos.  You will get two new photos from Bing each week, through an RSS feed.

You can download the Dynamic Bing wallpaper here.
