Ad!dict Creative Lab, a Belgian design house, recently sponsored a lab to showcase 60 or so design projects working with chocolate. A series of designers reimagined how chocolate looks, how customers relate to chocolate, and how it fits into the overall culture. The Ad!dict site has a list of the projects. I particularly like the bar design that shows who gets the revenue from the sale of the chocolate, and the peaceful Zen stone chocolate.
