I was a guest speaker/presenter for the Graphic Design program in the Art Department at Central Michigan University, November 12–13, 2013. On the evening of November 12, I gave a talk called “Singing the Surface,” and followed the next day with a presentation of my “Graphic Equalizer,” after the essay in my book Volume. Thanks to David Stairs of CMU and Designers Without Borders for the invitation, and the brave/inquisitive students and faculty that came to the events.
