title: What technology is used at the Google homepage (guitarstrings)
body: <p>What technology is used at <a href="http://www.google.be/" rel="nofollow noreferrer">the Google homepage</a> (9 June 2011)? They made something like a guitar pickup for the snares. When you move the mouse over it, the snares are being played.<img src="https://i.stack.imgur.com/AFUIE.png" alt="enter image description here"></p>
  
  <p>I know it is no flash, otherwise the add-on for Firefox would have blocked it.</p>
  
  <p>Thanks.</p>
