This is a short film by three students at the 3D school Supinfocom Arles in France. It tells the story of a Peruvian boy and his llama who find a letter dropped from a mail plane. The boy makes an airplane from the letter and a wild psychedelic ride ensues. The setting and style of the boy and his home remind me somewhat of the Disney movie The Emperor's New Groove. The story is however completely original.
