Just found this and it works really well even on snow leopard. And best of all it's free. http://www.dativestudios.com/docklibrary/ I just donwloaded some free patterns to try it out here. http://leoparddocks.com/index.php Import zip file and activate. Takes 2 seconds. Now if I can only have my old rainbow back that would be nice. I guess that will be the next test to make my own and see if it works. If I extract a pattern and right click and say compress. It also imports. So it works just as the original. So it shouldn't be too hard to make my own designs and rezip them. I just don't remember what info.plist does or how to edit that if I use my own design.
