Look at me! Did that scare you? ;-)  Because it's pretty freaky, if I may say so myself. As much as I would like to take credit for this zombie effect, I didn't have to do any work to achieve the ghoulish look (unless you call clicking on some buttons "work"). So no, there will be no makeup tutorial. :-P What I can tell you is that you can easily do the same for yourself, or any other person's portrait. All you need is a Google+ account...
