Moving Desktop Backgrounds Biography

Animation refers to the recording of any image which goes through changes over time to portray the illusion of motion. This is usually accomplished with a camera and a projector or a computer viewing screen which can rapidly cycle through images in a sequence. Animation can be made with either hand rendered art, computer generated imagery, or three-dimensional objects, e.g. puppets or clay figures, or a combination of techniques. The position of each object in any particular image relates to the position of that object in the previous and following images so that the objects each appear to fluidly move independently of one another. The viewing device displays these images in rapid succession, usually 24, 25 or 30 frames per second.Evidence of artistic interest in depicting figures in motion can be seen as early as Paleolithic cave paintings. Animals in these paintings were often depicted with multiple sets of legs in superimposed positions. Because these paintings are prehistoric they could be explained a number of ways, such as the artist simply changing their mind about the leg’s position with no means of erasing, but it’s very likely that they are early attempts to convey motion.

Another example includes a 5,200-year old earthen bowl found in Iran in Shahr-e Sukhteh. The bowl has five images painted along the sides, showing phases of a goat leaping up to nip at a tree.An Egyptian mural, found in the tomb of Khnumhotep and Niankhkhnum, at the Beni Hassan cemetery includes a sequence of images in temporal succession. The paintings are approximately 4000 years old and show scenes of young soldiers being trained in wrestling and combat.
