Google X was a project released by Google Labs on March 15, 2005 and rescinded a day later. It consisted of the traditional Google search bar, but it was made to look like the Dock user interface feature of Apple's Mac OS X operating system. Google did not release any official statement as to why the project was shut down. Apple has patent protection covering the implementation of the Dock effect, together with trademark protection for the graphical design elements of the Dock. Although Google X has been taken down, several mirrors still exist.
