A few years ago, I did a good job of carrying a small camera with me at all times, so that I could photograph any interesting composition that caught my eye. Since starting grad school, I’ve done a poor job of keeping up with this habit, however. Recently, I’ve been trying to get back in the groove, and in that spirit, I spent an hour yesterday at lunch photographing the procession of shadows across the wall in the lounge in the new CSE building at UW. The grated metal sun visors make for some excellent shadows, and it was fun watching how they changed every few minutes while chatting with my friends.
