title: Battlefield 3 logo effect
body: <p>For those that have Battlefield 3, could someone please explain to me how to recreate the effect that makes the logo 'shimmer'. I know the image has 3 states (mouse-out, hover and mouse-in) but I have no idea how to make it shimmer.</p>
  
  <p>The effect of the logo can be seen by logging into BF3 battlelog and mousing over the logo.</p>
  
  <p>Does anyone have any idea?</p>
