MacThemes.net has announced a new Tiger-compatible version of ShapeShifter, the program / hack that lets you customize the look and feel of OS X. This new version "includes support for the new system's spotlight metadata searching, the ability to skin the Dock, a new installer, several Tiger specific skinning abilities, and various bug fixes. Though themers should update their themes to take advantage of the update's new features, ShapeShifter will automatically upgrade themes on application for basic Tiger compatability." ShapeShifter costs $20. You can either download themes for free or hack your own.
