If you’re at MathFest, be sure to check out the art exhibit. I have a couple of pieces there, including a painting of the geometry of longitudes and a set of bracelets I made with cellular automata. You can see from my first photograph that I’ve done this painting more than once because I wanted to update it for the conference. In doing the second version, I screwed up one of the, illustrations in the center column and so I had to do it twice to get it right. #mathart #geometry
