模仿 "淘宝彩票" 的随机选球投注效果！
作者：互联网
我个人比较喜欢看网页的效果，前几天看了淘宝的“淘宝彩票”，今天仿造做了一个，我觉得比淘宝的体验要好。
查看 “淘宝彩票” 的网页源码发现，主要是用到了Css3 transform 的 Matrix 来控制小球旋转 。
参考了张鑫旭的Css3 transform 的 Matrix 文章：http://www.zhangxinxu.com/wordpress/?p=2427
我发现该效果主要用到了CSS3以及队列的知识：
[1]: 旋转效果：transform: matrix(1, 0, 0, 1, 0, 0); (这里还可以用rotate来实现旋转)
[2]: 队列: 用setTimeout来模拟队列
自制效果如图：演示Demo地址如下：http://www.imengwang.net/lottery/index.html#
