Dynamo
I found the above short animated film on DailyMotion, it took my a bit of Googling but I found some information on it:
“Dynamo is the graduation film by Fabrice Le Nezet, Mathieu Goutte and Benjamin Mousquet three Supinfocom students. It’a a 3D animated short made up to look like stop-motion. “Dynamo tells the story of two characters who live on a planet and work together to keep it rotating. The mechanics of the planet are dependent on its two inhabitants”, but one day it just stops.”
