This is your virtual window on Africa. You can select whether to have your desktop change on a daily, hourly or even near-real-time basis. It synchronizes your time zone with the cameras in Africa''s most active wildlife parks. You are guaranteed to see lions and other wildlife at least 5 times per day. The application is tiny, and does not affect the speed or efficiency of your machine - it updates your desktop wallpaper at the interval selected by you. The lion is said to be majestic, the leopard ferocious and shrewd. But elegant and graceful best describes the cheetah. The cheetah is smaller than the other two cats, but by far the fastest at speeds of 70 miles per hour it can run faster than all other animals. Now restricted to sub-Saharan Africa, wild cheetahs once were found in most of Africa, the plains of southern Asia, the Middle East and India.

The cheetah is built for speed. It has long, slim, muscular legs, a small, rounded head set on a long neck, a flexible spine, a deep chest, nonretractable claws, special pads on its feet for traction and a long, tail for balance. Although fast, the cheetah cannot run at full speed for long distances (100 yards is about the limit) because it may overheat. Cheetahs have distinctive black "tear stripes" that connect from the inside corner of each eye to the mouth that may serve as an antiglare device for daytime hunting. Cheetahs are found in open and partially open savannas. Cheetah mothers spend a long time teaching their young how to hunt small live antelopes are brought back to the cubs and released so they can chase and catch them. Unlike most other cats, the cheetah usually hunts during daylight, preferring early morning or early evening, but is also active on moonlit nights.

Cheetahs do not roar like lions, but they purr, hiss, whine and growl. They also make a variety of contact calls; the most common is a birdlike chirping sound. Once a cheetah has made a kill, it eats quickly and keeps an eye out for scavengers lions; leopards, hyenas, vultures and jackals will occasionally take away their kills. Although cheetahs usually prey on the smaller antelopes such as Thomson''s gazelles and impalas, they can catch wildebeests and zebras if hunting together. They also hunt hares and other small mammals and birds. Although known as an animal of the open plains that relies on speed to catch its prey, research has shown that the cheetah depends on cover to stalk prey. The cheetah gets as close to the prey as possible, then in a burst of speed tries to outrun its quarry. Once the cheetah closes in, it knocks the prey to the ground with its paw.
