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 giraffe''s high shoulders and sloping back give the impression that its front legs are much longer than the hind legs, but they are in fact only slightly longer. The giraffe (as well as its short-necked relative the okapi from Central African forests) has a distinctive walking gait, moving both legs on one side forward at the same time. At a gallop, however, the gait changes, and the giraffe simultaneously swings the hind legs ahead of and outside the front legs, reaching speeds of 35 miles an hour. Its heavy head moves forward with each powerful stride, and then swings back to stay balanced. Giraffes have "horns" not true horns but knobs covered with skin and hair above the eyes to protect the head from blows. The reticulated giraffe (Giraffa camelopardalis reticulata) of northeastern Kenya has large, chestnut-colored square patches defined by a network of fine white lines.

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.
