A twitter client written in php with php-gtk. For me, it's the best option for Linux, since adobe air alpha is so buggy.

You'll need php-5 and php-gtk in order to run this. See UbuntuHowto.

New 0.11 release, filter your tweets! Create groups of close friends and groups for the masses. Don't miss your friends tweets anymore! New menu option to set up/modify filters.

Download version 0.11 (beta) here: http://phpitter.googlecode.com/files/phpitter-0.11.tar.gz

There is also a php/php-gtk packaged download for windows available here: http://phpitter.googlecode.com/files/phpitter-php-gtk-win-0.11.zip. Just download that and double click "run_phpitter.bat".

I'm trying to make it easy to write plugins for useful hooks. Right now there are 3 hooks implemented:

1. entryChange. This gets called whenever the tweet entry box is changed. One plugin is provided that turns the text red if it's > 140 characters.

2. newUpdates. This gets called whenever new updates are retrieved. Two plugins are provided, one just echo's to stdout who tweeted what, the other uses libnotify's notify-send to send a popup down in the corner.

3. displayTweet. This gets called on the text of a tweet before it is displayed. Two plugins are provided, one turns @name's in to clickable links, the other turns http:// style urls in to clickable links.

Here are some screen shots:
