This extension is a theme for Google Chrome. It modifies the look of your browser, and nothing else. This particular theme will change the toolbar to a light pink colour, your open tabs will be a transparent blue colour, and the background of your search page will be an image by artist Steven Sugar. The image is a cartoon and stylized rendition of clouds, with the colours pink and blue being highly featured. The moon is also visible, hence the name. Hope you like it! :)
