I am quite happy with the way my desktop looks so I decided to upload all the files to share with everyone.
Use OS-X.5-Window-Border.tar.bz2 for GTK Borders
Use OSX-itunes-Controls.tar.gz for the Controls
You may have to adjust osx-top-bar-1680x1050.png to suite your resolution to use as the top panel background.
*Requires default MAC fonts.
Icons are from http://www.gnome-look.org/content/show.php/OSX?content=31618
