I've been working on a project in the background, and just recently petitioned sourceforge.net for an official listing. Basically it is an Ajax driven, modular groupware suite.
I got this idea as I looked for a nice, online address book. This led to finding several good groupware suites, such as the excellent phpGroupware, and PHPProjekt. While these are great apps, I really didn't need such beastly and large applications. So I designed a quick address book, and decided to use Cody Lindley's thickbox to add a coolness factor of, like, a zillion.
While it may have been way cool, it still wasn't quite what I wanted. Given recent developments in my programmer-life I've decided to start anew. I intend to make a windowed environment, similar to the windowing system that is on my index page. I'll also tie in lots of ajax and plenty of moo.fx for bling. I'm also going to use the smarty template system to make it sleek and easy to customize. I'll keep you posted.
