Every year December means the end of the year, and also the start of a new one. We decorate our houses to mark the festival mood of Christmas and exchange gifts. For many of us who spend long hours in front of the monitor more than any other place of their homes, here are some cool wallpapers to decorate your monitors to welcome 2012.
