scripty2 is a complete rewrite of the venerable script.aculo.us library. It is a powerful, flexible JavaScript framework to help you write your own delicious visual effects & user interfaces.

However, scripty2 is still in a prerelease alpha version and not meant for production use at the moment. Even in alpha, the effects engine can now do so much more, with less code to write.
