Alienware, who make some of the coolest (and most expensive) PC's on the market commissioned Stardock to create a custom complete Windows skin for them. The new skin will be pre-installed on all of the new Alienware machines and if you go to their ordering system you'll see that it's already listed as a feature.
The cool thing is that Alienware has also released the custom skin into the community as a free download! Yeah, it's also free advertising for them but it's a pretty cool skin for sci-fi fans.
The download is pretty big at roughly 40 megs so if you're on dial-up you may want to get a friend with broadband to download & burn it to CD for you. Even with my Verizon DSL connection it still took me over an hour to download it because of how busy the Alienware download servers are right now.
To grab yourself a copy go here to get more information about the skin and view some screen shots at the bottom of the page. If you like what you see click on the download button the right side of the screen and you'll then be prompted for an email address. The email address is for nothing more than to join their newsletter list so just enter a bogus one if you don't want to be on the list. After entering the email address you'll then be redirected to the download link. You may want to copy the 2nd link in case the servers are busy and you get a timeout.
