How To Install a Custom iTunes Skin
Skins on this page are for iTunes 6.0.2 running under Mac OS X, they are not compatible for use with any installation of iTunes for Microsoft Windows.
Some skins may use installer packages as their switching method. Others require you to manually switch out the iTunes Extras.rsrc.
1. Control-Click on iTunes.
2. Select Show Package Contents.
3. Open Contents folder, then Resources folder.
4. Make a copy of the original iTunes.rsrc file.
5. Install new iTunes.rsrc (skin) and have fun!

NOTE: You may need to add iTunes to ShapeShifter's exclude list if the skin appears to have not been applied.
