They're hiding in your closet. They're lurking in your bed. They're all over you--snacking on your skin, burrowing through your scalp, munching on your mascara. They're the creepy crawlers of the unknown world, and now--thanks to micro-photographer Lennart Nilsson, who brought us The Miracle of Life--you can (shudder) catch these critters in the act, magnified to monster size.
