Hello, I found these two coin videos on youtube. The first is hand drawn maze of a Buffalo Nickel. http://www.youtube.com/watch?v=7fE3tfe17oA The second is of a modern Shield Penny. http://www.youtube.com/watch?v=ZViKF81Nxtg What makes these videos so cool is that the artist draws them on camera and then solves them to show hidden messages or pictures. I do not know how he does it but these are amazing. (No pun intended.)
