Growl for Rails Built on Prototype and Scriptaculous

Growl4Rails is a javascript component that provides the UI for growl-like notifications in your Rails web application. Jim Fiorato has recently added the ability to show multiple growls at once, as well as improved support for IE. You can also specify the duration and max number of growls to show.

If you are not using Rails, you can also get the Growl for jQuery and Growl for Mootools instead.

Requirements: Rails 2.1+, Prototype 1.6+, Scriptaculous 1.7+
