A few months ago, Peter "The Man" Shin started working on a new theme for Liferay, called, appropriately enough, Desktop.

Yes, I know we already had a theme called Desktop, but to be honest, it wasn't the greatest theme in the world. The different "OS's" was actually just different backgrounds on the same theme.
So, to the rescue, Peter went through and created a new theme, with 3 real OS versions included in it, which I've shown below.

If you get a chance, tell Peter how much the theme rocks by emailing him at "P shin @ liferay [dot] com" (use your mental regex engine to parse that one out :) ).

How do you get the theme? Download the latest bundle of Liferay (4.4.0), and go to your Plugins page, which is located in the Welcome dock > My Places > My Community > Private Pages. Click on the Theme Plugins tab, and you should see the Desktop theme.

Click on the link, and press the Install button, and you're all set.

I'll be blogging on the best way to do this soon, so users can see what the process looks like.
