It seems that Google's 'Google X' interface is kind of a hot topic on the Net right now. Google created it as a MacOS X like interface for its search engine. Soon after Google released it, they took it down (maybe for legal reasons).
To see what all the controversy is all about, this web site has posted a mirror of the original interface. As you move your cusor over the icons, they will grow larger then smaller as you move off of them.
