Colin Purrington, a professor of evolutionary biology at Swarthmore College, has a great photostream on Flickr in which he documents and comments on explanatory labels at zoo exhibits. His spot-on commentary brings issues of zoo audiences, effective communication strategies, and good design together for a great examination of information design.
