In response to the theme of Object Oriented Ontology. I made a short 2D animation, which shows a bird built an nest with LED lights, and the lights flickered at night to illuminate its lovely bottom. By drawing three animation key frames in Procreate and making transition for them in Premiere, I wanted to show a series of interactions between bird and LED lights: the bird uses lights to build its nest, and the lights in turn illuminate the bird. Similar work has been produced by Pixar Animation Studio, whose film Walle also explore the same theme by showing the unique knowledge of cleaning robots for various objects. Another similar work is NieR: Automata, a game developed by Square Enix and PlatinumGames. This work also explore this theme by showing the scene of the city being invaded by huge vegetation after the extinction of mankind.
