An unofficial Google Chrome Theme for the Hobbit - An Unexpected Journey.
This theme is featuring a wallpaper from the upcoming second or thirth part of the Hobbit series. There will be three movies in total, both directed by Peter Jackson-- just like the Lord of the Rings.
It was very easy to make this theme for there was just an image being released featuring a whole bunch of wallpapers in one. You can find it right here: http://goo.gl/7z9Ss
