The sequence of updated backgrounds for the Bing Dynamic RSS Windows 7 theme continues this week with two new additions for the collection.

These new backgrounds bring the total count in the theme to 40 and you can see all of them at the Bing Dynamic Theme RSS feed.

Although this RSS feed will only work with Windows 7 to retrieve the backgrounds as part of a theme but if you access that RSS feed linked above you can individually download each background for use on your computer system. 

Here are the two update from this week:

Crown jellyfish (Netrostoma setouchina) in the water near Niue, South Pacific

Jelena witch hazel (Hamamelis x intermedia)
