I love the idea that the design plays on a chocolate bar as a pharrmaceutical drug. Bloomsberry & Co’s line of high end chocolate bars plays with this witty packaging which is quite refreshing.
Rebecca Bibby has also designed a chocolate wrapper which references pharmaceutical design from the mid-late 20th century. Each flavour is represented by a block of colour and an element symbol, similar to the periodic table. http://www.thedieline.com/blog/2012/1/24/student-spotlight-elixir.html
