I found this over on the ThemeXP site...
- Apple has contacted ThemeXP and notified us that we are in violation of Apple's copyright on OS X by hosting two themes: "EclipseOSX v4.40" and "MacOSX Aqua 3.2". As much as we enjoy long and expensive lawsuits against mega-corporations, we decided to comply with their notice of infringement and take down both of the two themes we previously hosted.
The two themes have been pulled from ThemeXP, but i'm sure that they are available elsewhere... ;)
