I do'nt think anybody has mentioned it, but the princible behind Flash is that it produces works with vector files for its animations. Some graphics are pixel based, meaning they have a finite demension i.e. 1024x769pixels. They lost thier sharpness when they are displayed larger than they were saved. Say yoiu have a 200x200 pixel photo, if you were to try to cover your whole screen with it it would appear very degraded. With a vector image the graphic is saved as a mathmatical equation. This equationcan be dislpayed at any size, without quality loss. A vector logo displayed in the corner of a screen would look the same way plaster along the side of a skyscraper! = )
