Below is a one-page graphic overview of the theory produced for the Purdue Polytechnic Institute (PPI). The document is open-licensed and available online (as you can see),
so yes -- feel free to share this with your friends however you would like.
Special thanks to Emily Dringenberg (Purdue University) who introduced me to this theory last year, and Lindsey Vanderlyn (Olin College) for thought-provoking conversations on applying it to computing education.
