Twoot is a customizable minimal twitter client for WebKit-based SSBs. It is based on jQuery, Fluid and some basic HTML and CSS. The idea is to provide a native-looking application that is easy to customize to your specific needs.
This version was forked from Travis Jeffery's version.
Put all Twoot files in a folder somewhere. Download Fluid and create the Twoot.app by following the instructions here:
Launching the app will prompt you for your username and password on the first run.
The code should also work directly in Safari and other WebKit-based browsers (including the iPhone).
The idea is that you should adapt Twoot to fit your requirements. If you know HTML and CSS it is trivial to add a new style. Create a new folder under the style directory and add all style files (css/images) there. Don't forget to change the stylesheet link in the twoot.htm file.
