Creating Animations

Animation can be an important part of your application or website, whether the focus is on e-commerce (attracts attention and provides product demonstrations), education (simulates complex processes such as DNA replication), or entertainment (provides interactive games).

The perception of motion in an animation is actually an illusion.  Animation is like a motion picture in that it is made up of a series of still images.  Our eye captures and hold an imae for 1/10 of a sec. before processing another image.  By retaining each impression for 1/10 of a sec., we perceive a series of rapidly displayed still images as a single, moving image which is known as persistence of vision.
