Btw on page 2 of responses, the author posted this download link to get the theme.

Personally I wouldn't do it for three reasons: 1) I prefer the default OS X look, 2) this is a fairly obscure thing & if you don't know the author how can you trust his code?, and 3) system hacks tend to be broken by software updates (then those people come here with "OS X problems").
 
I'm pretty sure he's running Windows, just tricked out to look like OSX, he mentions running AveDesk, Miranda and his own special about this mac program.
 
its windows XP running a few 3rd party apps like avedesk and objectbar

i've done it on XP too, it just LOOKS good, doesn't perform half as well to the OS X equivalent
 
Yeah, the only thing that the file from the author's link does is skin the "About this Mac" box...the rest of the "theme" is just some concept art.
