title: Java (2D) animation library
body: <p>I'm creating (for a semester project) a Java desktop application. The aim is to provide a rich and intuitive user interface. I'm now looking for Java cross-platform library that works with Swing and provides animations (moving, resizing, rotation, color/alpha change and other 2D stuff).
  Basically, I'm looking for an equivalent of <a href="http://developer.apple.com/graphicsimaging/coreanimation/" rel="nofollow">CoreAnimation</a> in the JavaWorld.</p>
  
  <p>I found <a href="http://kenai.com/projects/trident/pages/Home" rel="nofollow">Trident</a>, but have no experience with it and no development seems to have taken place since mid-2010.</p>
  
  <p>Does anyone of you have experience with Trident or can recommend a library that fits what I need?</p>
