* ARCTIME = 1333ms (time it takes to expand and contract arc)
* ARCSTARTROT = 216 degrees (how much the start location of the arc
* should rotate each time, 216 gives us a
* 5 pointed star shape (it's 360/5 * 3).
* For a 7 pointed star, we might do

/**
* IMPORTANT NOTE ABOUT CSS ANIMATION PROPERTIES (keanulee):
*
* iOS Safari (tested on iOS 8.1) does not handle animation-delay very well - it doesn't
* guarantee that the animation will start _exactly_ after that value. So we avoid using
* animation-delay and instead set custom keyframes for each color (as redundant as it
* seems).
*
* We write out each animation in full (instead of separating animation-name,
* animation-duration, etc.) because under the polyfill, Safari does not recognize those
* specific properties properly, treats them as -webkit-animation, and overrides the
* other animation rules. See https://github.com/Polymer/platform/issues/53.
