title: Where is DeviceMotionEvent currently implemented?
body: <p>The <a href="http://dev.w3.org/geo/api/spec-source-orientation.html" rel="nofollow">DeviceOrientation specification</a> includes a Device Motion Event. I've seen it run on an iPhone, and heard it is supported in Chrome Mac and used on the <a href="http://www.google.com/logos/verne.html" rel="nofollow">Google Jules Vern Doodle</a>.</p>
  
  <p>Is it supported in any other browser implementation yet? What versions did it become available in?</p>
