GoogleX was a fine product of Google Labs. It was an homage to OS X’s dock. And as expected, Apple got mad and made them take it down. A search for GoogleX on Google still returns the original URL for GoogleX as the first (and second) search result, but the page only contains these words:
The requested URL was not found on this server.
I had completely forgotten about this site until yesterday, when I stumbled upon a mirror. And as luck would have it, the host of the mirror has the entire site zipped up in one small file for downloading. Now I have my own GoogleX mirror. :)
