I saw a press release today for an app called "ZombieBooth." This was a little weird because I had downloaded the app earlier on my non iOS tablet, as that had a camera on it. There is an iOS version also which works on your iPad2, Ipod Touch 4 or your iPhone which have cameras on it.
Basically, you can see what people would be like if they were zombies. These are not just pictures. There is animation involved. It really is pretty freaky, but it's fun.
The press release is below. You can see what the app is all about. The link below is to the free Lite Version. There are paid versions also.
