title: Using THREE.Gyroscope to keep an object facing the camera
body: <p>I've been trying to get my head around how the Chrome 100,000 Stars experiment uses <a href="https://github.com/mrdoob/three.js/blob/dev/src/extras/core/Gyroscope.js" rel="nofollow">THREE.Gyroscope</a> to keep an object facing the camera (<a href="http://www.html5rocks.com/en/tutorials/casestudies/100000stars/" rel="nofollow">as mentioned here</a>).</p>
  
  <p>I can't find any simple examples or documentation of THREE.Gyroscope with it working.</p>
  
  <p>I'm sure it's a simple thing to implement but I just can't work out how to create a gyro and have it keep a specified object facing the camera.</p>
  
  <p>Any ideas?</p>
