Colorized animations of microscopic insects rotating under a scanning electron microscope. The images were colorized by computing a 3D reconstruction of the insect and then transferring the color from a small set of example images painted by the artist Martin Oeggerli. The sequences were recorded for the National Geographics IMAX movie Mysteries of the Unseen World. Cat flea (ctenocephalides felis) Human head louse (pediculus humanus capitis)
