Screenwatcher

Screenwatcher is a movie player for websites, images, and screensavers. Unlike most players, Screenwatcher displays the movies on the desktop background.

Therefore you can display an RSS newsfeed or a YouTube video on your desktop. A configurable animation is shown when the player changes from the current movie to the next one. Screenwatcher supports multiple screens. The application is available in English, German, and French.
