纯CSS3炫酷animation动画steps属性打造西洋镜动画特效 A CSS Zoetrope

A zoetrope is one of several pre-film animation devices that produce the illusion of motion by displaying a sequence of drawings or photographs showing progressive phases of that motion.
The basic drum-like form of the zoetrope was created in 1833 or 1834 by British mathematician William George Horner. [wikipedia]
