This one will definitely interest movie buffs! Microsoft has released a Paramount Pictures Movies dynamic RSS themepack for Windows 7.
Dynamic RSS themes are updated by an RSS feed and as a result fresh wallpapers are automatically displayed on your Windows 7 desktop. These images get saved to a special folder and appear on your desktop automatically.
This theme will automatically deliver new wallpapers from the latest Paramount Pictures movies, including Thor, True Grit, Kung Fu Panda 2, Super 8, and Transformers 3.
Do note that some images displayed in this theme may be from movies that are not classified as suitable for young children.
Go here to get it.
… And get ready to be surprised, every so often!
