Vietnamese-American artist Binh Danh, a graduate student at Stanford, makes photographic prints using leaves and preserves them in resin. Chlorophyll, the key chemical of photosynthesis and hence directly or indirectly vital to almost all life on Earth, is (obviously) sensitive to light, and consequently leaves change color in response to light exposure. Binh makes striking prints of images from the Vietnam War. Here’s a slide show of them and links to more information:
