Love the idea on the website, The 99% Behind the Money. This site features photos of a face on a paper bill (i.e. Jackson on the US $20) that morph into your friends real face. It is real simple to do. Basically, you take a paper bill, fold it in half. Than position it between the camera and the subject (person) to be in the photograph until the bill face matches the real face. Then shoot away! When you have just what you want, you may upload and share on this website for shits and giggles.
