The little things in life are sometimes the most meaningful, and with the right equipment and artistic eye, the most beautiful. That's how Nikon's Small World photography competition sees it. Founded in 1974, the contest showcases the beauty and complexity of light as seen through a light microscope. For 2010, the winning photomicrographs include: colorful, psychedelic soap-film bubbles, cancer cells that appear as flowery pom-poms and an alien-like portrayal of a bird of paradise seed. Here's a look at all the winning photos.
