Paper-Kit have developed a system to use a 2D printout to turn yourself into a full 3D model.
The first process is to upload some photos taken from left, right and front sides of your head. The software automatically maps that into a 3D polygonal model which can be tuned perfectly so eyes, ears, nose and mouth all match up.
The software flattens the model and generates a PDF file that costs only $2 to download. This is printed to make the 3D model. The only issue is currently long hair, as the software can't handle ponytails and other styles.[yframe url='http://www.youtube.com/watch?v=Nw_WELwh7aU']
The finished paper model looks fairly realistic, almost like a 10 year old computer game representation of a person and ideal for special events or funny parties!
