SCREENSAVER DESCRIPTION: Come on a camel caravan across the desert dunes. The tranquil beauty of these desert scenes will calm your mind. Each dune is unique and beautifully sculpted by the desert winds. These 28 images will take you into the vast desert where you will see towering dunes, magnificent sunsets, and scampering lizards and dung beetles. The Arabian and Sahara Deserts are the most well known sand deserts with undulating dunes, but Tunisia and other North African countries have striking dune landscapes. Dune deserts are also found in Australia and North and South America.
