Amuse has released My Living Desktop 4.9 (http://www.mylivingdesktop.com/) for Mac OS X, a new version of their video desktop and screen saver utility. The upgrade is ready for Mac OS X Lion and adds new scenes.

My Living Desktop is a cross between a video desktop (moving wallpaper) and screen saver. With its built-in video importer, users can import their own movie scenes for use as video desktops. Anyone can have family movies, movies of friends and special events, vacation movies and more as their desktop — or as a screen saver.

My Living Desktop boasts a variety of high-definition movie videos shot from all around the globe, accompanied by nature sound effects. Upon purchase, download access to additional hi-def movie videos are available from within the software itself.

The application also sports Automatic Serenity Breaks. This feature allows the user to have My Living Desktop automatically remind them to take a break. Simply specify the interval or time(s) of day and a sound chimes, all work is faded into the background and the entire screen converts into a playing scene.

Among My Living Desktop’s features is its ability to automatically mute its sound at appropriate times. For example, when the user launches a music player, My Living Desktop can disable and/or mute itself. When the user finishes listening, it will automatically turn back on. Users may designate any set of applications for which My Living Desktop disables itself or mutes.

My Living Desktop can also be set to recognize when the user’s laptop is operating on battery power, and disable itself to conserve power. The app turns back on when the user plugs into a power source.

The software requires Mac OS X 10.5 or higher. My Living Desktop 5.0 costs US$34.95 for a single-user license and $49.95 for a five-user license. Version 4.9 is a free update for registered users of version 4.x.
