EarthView is a fairly cool dynamic desktop background/wallpaper + screensaver program that only takes earth as its theme, developed by DeskSoft from Austria. It gives us a direct bird's-eye view of the earth from outer space on desktop, and shows the shift of day and night (i.e. the daylight zone and dark area at night) and the atmospheric cloud changes in a dynamic way, which can give users a stunning visual experience.

DesktopPlant is a very interesting and cool electric virtual planting program. It allows you to grow several common ornamental plants on your desktop to bring some vitality. They also do need you to take care carefully, just like the real flowers in life.
