This is just a modified Version of the excellent "Silver XCursors 3D" Theme (http://www.kde-look.org/content/show.php/Silver+XCursors+3D?content=5533).
Actually it is the "old" Version with full animation, but with the pirate cursor, repacked for easy install (e.g. in KDE).
I am not the author of this theme. I just re-uploaded this version, because i couldn´t find it anymore on kde-look. All the credits go to the original author. Thanks for the great work.
