A CodePen by Chris Coyier. Hover Animation from UNIQLO - From pages like this: http://www.uniqlo.com/us/mens-clothing

Only they use an [animated GIF](http://www.uniqlo.com/us/published/b861cf4a/img/barberpole_5.gif) and this is CSS only. Would have like to not do the extra `div` for the hover, but there is no background-opacity...
