Thomas Fuchs just today announced that script.aculo.us 2 is out of alpha, and now have a new domain named Scripty2 with complete rewrite code and new features. It’s a powerful and flexible JavaScript framework to help you create next-generation HTML-based visual effects and user-interface. You can check out the awesome cards and puzzle working demo accordingly.

Scripty2 was divided into three parts, core, fx, and ui.

• scripty2 core: helpers for a more delicious developer experience; core contains various JavaScript and DOM extensions used by scripty2 fx and scripty2 ui, plus developer utility classes.
• scripty2 fx: the framework for DOM/CSS-based visual effects; The scripty2 effects framework provides for time-based transformations of DOM elements and arbitrary JavaScript objects.
• scripty2 ui: user interface behaviours; functions for CSS parsing, color normalization and CSS value interpolation.

The API is still not available yet. For more information, please refer to their doc page and Google Group.
