Make sure to watch through to the end of the credits.

From IMDB:

– Jonas Geirnaert (then 21 years old) was a student animation and hadn’t even graduated, when he came upon a registration form for the Cannes Festival on their site, decided he had nothing to lose and sent in his “graduation-work”. He had told nobody, thinking he wouldn’t even be selected anyway. To his surprise, he won in the category “Best Short Film”.

– Geirnaert drew all of the animation (more than 9,000 drawings) himself. It took him two years. The sound however he had to prepare in less than half a day, because the deadline for sending in the work to Cannes had actually already expired.

– The version of the shortfilm that won the Jury Award at Cannes was an unfinished version.
