Artist Juan Fontanive (previously) constructs ornithology-oriented flip books which constantly loop with the help of a few hand-built mechanics. The still images are sourced from 18th and 19th-century natural history illustrations, and when combined imitate the motion of a bird in flight. Although these works were completed this year, Fontanive has been working on the series since 2004 while he was studying at the Royal College of Art. Previous animation explorations have featured butterflies and birds drawn with graphite and colored pencil. You can see more of his automated sculptures on his website and Vimeo.
