Via Metafilter, a fantastic multi-page development log for a portable apparatus for photographing flying insects. A camera with locked zoom is triggered by an electric eye monitoring the focal plane. The whole deal is worn in a harness and looks a bit like a dowser's water stick.
My favorite are the early failures, e.g. a bumblebee almost out of the frame (every other bug is too fast). Then, after machining his own shutter, triumph.
How sweet it is.
