First off you will need to download 3 applications Magnifique ThemePark Mirage. When you've done that download this file and unzip it. Open Magnifique and drag Tiger.mfq.plugin into the sidebar and apply the theme (DO NOT logout or quit any application yet!). Then open the Tiger theme file this will automatically run ThemePark after that apply the theme then quit all applications and logout. After you login open mirage and install the dock and separator after its finished navigate to /System/Library/CoreServices/Dock.app/Contents/Resources/ and drag and drop the files called indicator and separator. After that drag the folder to your Applications folder and run TigerDock.app (to make it run on startup open system prefs and go to Accounts > Login items and drag it into the window). Finally navigate to /System/Library/CoreServices/Search.bundle/Contents/Resources and replace MDSearchMenuIcon.pdf then logout and enjoy. Do not try this on anything but Snow Leopard.
