特效介绍
基于Aui-core和css3实现的带倒影效果的立体图片走马灯旋转特效，刚载入时，图片像发牌一样，一张一张有序的展开，围绕中心点立起来，鼠标左右拖拽旋转像走马灯一样旋转，可以查看任何一张图片。图片下有投影效果。图片可以无限增加，在js中配置即可。
使用方法
1、在head之间加入下面的css
<style>
*{margin:0;padding:0;list-style:none}
body{overflow:hidden; background:#000;}
#stage{width:200px;height:300px;position:relative;margin:0 auto;margin-top:150px;background:null;-webkit-transform:rotateX(-10deg) rotateY(0deg) perspective(2000px);-moz-transform:rotateX(-10deg) rotateY(0deg) perspective(2000px);-ms-transform:rotateX(-10deg) rotateY(0deg) perspective(2000px);-o-transform:rotateX(-10deg) rotateY(0deg) perspective(2000px);transform:rotateX(-10deg) rotateY(0deg) perspective(2000px);-webkit-transform-style:preserve-3d;-moz-transform-style:preserve-3d;-ms-transform-style:preserve-3d;-o-transform-style:preserve-3d;transform-style:preserve-3d}
#shadow{position:absolute;left:50%;top:50%;width:1200px;height:1200px;margin-left:-600px;margin-top:-600px;background:-webkit-radial-gradient(center center,600px 600px,rgba(50,50,50,1),rgba(0,0,0,0));background:-moz-radial-gradient(center center,600px 600px,rgba(50,50,50,1),rgba(0,0,0,0));background:-ms-radial-gradient(center center,600px 600px,rgba(50,50,50,1),rgba(0,0,0,0));background:-o-radial-gradient(center center,600px 600px,rgba(50,50,50,1),rgba(0,0,0,0));background:radial-gradient(center center,600px 600px,rgba(50,50,50,1),rgba(0,0,0,0));-webkit-transform:translateY(200px) rotateX(90deg);-moz-transform:translateY(200px) rotateX(90deg);-ms-transform:translateY(200px) rotateX(90deg);-o-transform:translateY(200px) rotateX(90deg);transform:translateY(200px) rotateX(90deg)}
#stage dd{height:300px;width:200px;position:absolute;left:0;top:0;border:1px solid #666;-webkit-transition:500ms all ease;-moz-transition:500ms all ease;-ms-transition:500ms all ease;-o-transition:500ms all ease;transition:500ms all ease}
.over{position:absolute;left:0;top:320px;width:200px;height:300px;overflow:hidden;-webkit-transition:2s all ease;-moz-transition:2s all ease;-ms-transition:2s all ease;-o-transition:2s all ease;transition:2s all ease;-webkit-transform:scale(1,-1);-moz-transform:scale(1,-1);-ms-transform:scale(1,-1);-o-transform:scale(1,-1);transform:scale(1,-1);background-size:100% 100%;opacity:0}
</style>
2、在页面中加入下面的容器，用来放置走马灯
<div id="stage"></div>3、引入aui-core库
<script src="http://www.5imoban.net/download/Aui-core/aui-core-1.42.min.js"></script>4、初始化插件
