Icon Module
I am currently thinking of creating a Drupal Icon module (for a Google Summer of Code project) that would allow users to choose a set of icons and apply them on a per theme basis. Currently I plan on creating a module that uses icon packs (a collected set of icons with a particular theme or design) to enable users to completely redefine the icons on their sites without the hassle of changing the actual CSS. I plan on making a module that supports the following features
-Allowing users to select different icons for different themes
-Allowing themers to define which icon sets their themes support as well as setting default icon sets.
-Allowing modules to add or replace icons through the Icon module
-Allowing users to create, upload, and download icon packs and share them with the community
Does anyone else have any ideas about what kind of features this kind of module should have. Thanks

Yeah!
Done right, that could be a great module.
I found when adding icon support for the Tapestry theme, that I needed to make special accomodations for IE6 and its weak PNG support. A number of GPL and CC icon sets that are available use PNG transparency, and won't render correctly in IE6. Using a javascript-based PNG fix for a page with potentially dozens of icons was not practical from a performance standpoint. I ended up adding a feature that allows you to specify a different icon set for IE6 vs. more compliant browsers. This allows the theme to use, for example, GIF icons for IE6 and PNG icons for everyone else. Not sure if this is the most elegant solution, but it worked for my beta-testers.
Drop me a line if I can help in any way.
I have the same plan!
Cool!
In fact, I had a wider plan: Making a set modules for changing look of drupal. one part of it was creating a module for selecting Icon Packs. Main feature should be an API for other modules to incorporate it into them easily.
If you decided to work on this subject, I would like to be in contact with you and analyse the needs.
Adding icons to menus
How about --
Allowing admins to redefine the menus with icons and or with or without text?
Sometimes plan text menus gets pretty boring... nothing says spice like a graphical icon!
(not sure if currently there is a module that does that or not)
