FaceOnBody is the first software ever created exclusively for digitally swapping faces 

FaceOnBody allows users to alter digital photos so that any face can quickly and easily be copied onto any body. No high-tech computer mastery is needed to create hilarious photos of yourself, friends – or, even enemies. FaceOnBody uses a simple drag-and-drop technology that allows even the most non tech-savvy users to make lifelike keepsakes.
