Imagine a desktop that looked and sounded like the great outdoors, introducing a sense of freedom to those stuck inside all day.
What Natural Desktop Does
Natural Desktop is an application designed to offer a good 'view' right from your desk, for those individuals who need a little nature in their window-less cubicle. The basic idea is to provide a constantly-changing wallpaper to your desktop to provide different wallpapers depending on the time of day, as well as the season of the year. The program also features sound effects, which can be disabled if desired, to lessen the boredom of many office jobs. A small 'widget' in the corner of your screen also provides up-to-date weather information so that you're always aware of what things are like outside.
How to Use Natural Desktop
Using Natural Desktop is straightforward. Once the app is configured, its just a matter of admiring the wallpapers, and enjoying the blissful sounds of nature. If you're wondering what the weather is like outside, the forcast is only a couple clicks away.
