This very cool op-chart was published in the December 27, 2009 New York Times.
I could see students using this as a model for the last ten years in their life, their school's history, or as a series of "learning" logs about the things and people they learned from in a Math class....very versatile model for a wide range of visual assignments....
Nice, so you're looking for the "special feature" where we get the behind the scenes doc:) Looks like it has a single author as it is presented as a visual op-ed.
