原生javascript+css3编写的3D魔方动画旋扭特效

一直从事于后端编程工作，工作中也经常接触和使用一些前端技术，但大多数还是用于操作和控制数据与客户端交互工作。随着互联网技术的发展以及硬件性能的不断提升，人们对于交互式体验已变得越来越重视，进而前端技术已经越来越突显出它的重要性，特别是一些炫酷的特效，精美的UI设计，都使人眼前一亮，顿时觉得网站平台都高大上不少，很博人们眼球，给人们以很好的视觉冲击，特别是现在的css3,HTML5技术的更新，使得以更小的代价就可以轻松实现这些效果，故此，顿时膜拜起前端技术，悠然起了兴趣，跃跃欲试，随机利用css3的新增3D特效技术及动画特效功能加原生态javascript写了一个随机打乱旋扭的魔方，在指定的步数后，魔方按记录的动作，逆行旋扭重新归位。随即发布出来与大家分享，也希望前端的大牛能指点一二，不甚感激！

注：在此基础上可以加上鼠标控制事件，可以直接通过鼠标控制器任意方向的旋扭，也可以稍加改进用于炫酷展示图片！后续有时间我将加上这些功能，与大家再次分享！
