Seaside provides a complete integration with script.aculo.us, allowing the use of the library without having to write a single line of Java Script. Everything can be configured and plugged together using Smalltalk objects.
The latest version of the package can be downloaded from SqueakSource at http://www.squeaksource.com/Seaside.
There is a web-site with a collection of life-examples at: scriptaculous.seasidehosting.st.
Some other examples (including drag and drop, sortables, effects, etc.) are included with the distribution.
