Also included with this release of the Toolkit is some of the new client-side animation support that is starting to come online. The animation package can be used both directly from JavaScript, or via a new control that you can use to easily compose animation behaviors (for example: you could have text or an image fade in, expand, explode, move, pop-up, etc) in response to user action. What is cool about the Animation package is that you can optionally define animation behaviors declaratively using the control, which makes defining animation sequences clean.
