Natural Desktop is a cool new program that looks at your local weather conditions, time of day and time of year and based on that sets your wallpaper, portal animation, and can optionally play a natural sounding environmental sound track. The wallpapers was created by Digital Blasphemy. The weather portal created by Tiggz, and the sound track from famed composer Mason Fischer. The result is just phenomenal, a must-have for anyone who is stuck in front of a computer all day.
Version 1.1 adds a bunch of customization options such as being able to select your own background sounds, wallpapers, locations, as well as control what the whether conditions (Example: Today I set it to play the raining/thunderstorm sound which can be quite relaxing).
Version 1.1 is free for those who have already purchased it (use Stardock Central to get 1.1 if you have 1.0). It also has some additional performance tweaking and performance options available.
