几个google彩蛋，很好玩！
到Google搜索：1）let it snow（屏幕就会开始下雪，结成雾后还可以写字）
<img title="snow" src="http://www.wpmes.cn/wp-content/uploads/2011/12/snow-500x258.jpg" alt="" width="580" height="299" />
2) tilt 屏幕倾斜

3）do a barrel roll 比较有意思，网页翻滚！
<img title="fangun" src="http://www.wpmes.cn/wp-content/uploads/2011/12/fangun-500x480.jpg" alt="" width="500" height="480" />
有意思吧，你也来试试！
