Okay here's the saga:
The original is by Mandla. I just changed the globe of IYY’s version to fit the Gnome 2 icon theme. You can find all files at http://ubuntuforums.org/showthread.php?s=762e21780e028282065c0a7ce7dbfcc1&t=273757.
The archive contains the SVG image and PNG bitmaps of several sizes. The directory tree is organized as specified in the freedesktop.org Icon Theme Specification.
