For those of you who've envied the incredible beauty, high quality, and great selection of Mac OS X Dockbar icons on www.xicons.com , I have put together an article that outlines how to unpack and convert the icons for personal use with ObjectDock.
You can find all the information here: http://www.upforums.com/themerge/Article-1.htm
You will need Stuffit 7.5 and IconWorkshop (5.01 or later). The shareware versions will do.
Wincustomize would now allow me to post the converted icons at Wincustomize, for obvious legal reasons. But it is perfectly legal to share the information neccesary to doing the conversions personally. Enjoy the icons!
