On May 11, 2009, I gave a talk 'Dissecting and Folding Stacked Geometric Figures' at the DIMACS workshop on algorithmic mathematical art.
In the first photo, you can see me sitting at a table in the front of the lecture room. The light was rather low, and when I monkeyed with the color in the photo to make it lighter, it became almost black and white.
In the second photo, you see the beginning of my talk, with the title page. I don't know why all the photos were shot right at the beginning of my talk. Maybe I broke the camera!
