"Paleodex" is my high degree in graphic design diploma project. It is a mobile app made for children visiting the Paleontology and comparative anatomy gallery of the National Museum of Natural History of Paris. The highly colored and illustrated identity of the app contrasts with the gallery that essentially presents animals' skeletons. The app permits to generates real long gone animals by selecting animals characteristics. By reading informations displayed in the museum you can guess what characteristics will generate what animal. Once generated, the animal is shown in his environment in an animated screen that gives some informations on it. Every animal generated is kept in a collection section of the app and can be seen in augmented reality. Paleodex was thought as a playful way to get into the fascinating world of paleontology.
