I made a post a long time ago about a very famous set of pictograms. Yet, when Jamie asked me which post I made had the pictograms, I couldn't have told you to save my life. When I made that post I didn't know the term pictogram(at least I hadn't made that connection, which is something I am trying to work on...). Pictograms are exactly what we are creating right now. We are working our way towards a cohesive set of information graphics that collectively(and possibly singularly) tell a story. We are creating them to try to inform the reader successfully through image alone.
The NYPL Lion article is an example of what we are going through right now, yet for a much large client. It is interesting however to see the process of how the icon was created/updated. Most times you dont get the pleasure of seeing the process, you only get to enjoy the finished, polished product with no inner meat to be seen.
