If you have a Droid (i have an iPhone but luckily the fiance has a Droid.. Win-win)... i strongly recommend Zombie Booth. It's free and it turns anyone into a zombie. What's not to like? The app itself is fun too... after you zombie-fy someone, they try to bite your fingers when you touch the screen, along with other fun features. Thought i'd show you a sample... It's also what i look like in the mornings, true story.
