Here is a sweet French animated movie about Gerald who one morning woke up as Geraldine.
UPDATE: Thanks to Sir Lee for telling me about the original Arthur de Pins site, which has a better quality version of the video (see comments).
Arthur graduated from the Ecole nationale supérieure des arts décoratifs in Paris in 2000. He is working as an animator, illustrator, character designer, and director.
There is an absolutely delightful collection of some of his illustrations over at Paintalicious. Take a look! You will love them.
