AMC recently launched the "Dead Yourself" app for iPhone and Facebook, which uses your iPhone camera or webcam to take your photo, and gives you options to give yourself a zombie makeover.
The network blogged about it today, with step-by-step instructions (although it's pretty self-explanatory).
Check it out at DeadYourself.com.
The show returns on February 10. AMC released this poster for the midseason premiere last week. They also announced that The Walking Dead: Survival Instinct (the upcoming video game) will be released on March 26 in North America.
