This was the winner of the Award of Excellence at the SIGGRAPH animation festival. It was done by François-Xavier Goby, Edouard Jouret, and Matthieu Landour from France, but the movie has a distinct Argentine flair.
I wish I could find the other award winners online, but haven’t yet. They include The Ark, which is about
an unknown virus that has destroyed almost the entire human population. Oblivious to the true nature of the disease, the only remaining survivors escape to the sea. In great ships, they set off in search of uninhabited land untouched by the deadly virus. So begins the exodus, led by one man …
The third award winner, for Jury Honors, went to Dreammaker about a retired wizard, “the Dreammaker who once made the most beautiful dreams for people. Now he lives solitary for only one purpose, the creation of a special dream - his dream.” The synopsis sounds kinda cheesy, but the production value is high, especially since it was only one person, Leszek Plichta, that did all of it.
