I live in Colombia South America and there is a local chocolate factory that packs its chocolate bars in foil paper with the logos of the factory and inside there is also a small picture that you should stick in an album. During the annual convention it is a staple now to have a contest called chocogami (I know the right name should have been chocoori but this is the name that stuck) in which you eat the chocolate bar and then you fold whatever is pictured inside.Jeremy Shaffer was the winner fo the contest the first year I was there.
the Colombian convention was just last weekend and as usual there was the chocogami contest. You can see pictures of the models folded from the chocolate bar foil wrap at: http://www.flickr.com/photos/oscaroso
