When I started working in the graphic design field, my master said logos must be fixed. Fortunately things are changing, so this is the most spreaded example of dynamic logo realized for the United Nations Climate Change Conference held in Copenhagen in 2009. The only similar example I remember is the Netscape logo cited by Lev Manovich in the Language of New Media.
The work has been realized by okdeluxe, a London-based design studio focused on interaction design and the design of media experiences. Companies like this demonstrate how the world of graphic design is now infected by programming languages. Now this concept is more and more evident, in fact using tools is not the final stage of graphic design, now we are able to go inside code for designing tools by ourself.
