I saw the above work of art on pinterest a couple of weeks ago and I had to give it a try. I gave students a 'engineer' assignment. After practicing several ways of creating notans, I asked my students to create a notan using only one sheet of red and one sheet of white paper. Another goal for my students was to make at least 20 transitions (the whole class moaned when they heard this). Most students were able to accomplish more then 20 transitions. Check out all of them on our flickr site.
