Elephants Dream is a short movie made using mostly open source software. Blender was the main program used to make the movie. It began production in September 2005 and was released on March 24, 2006. It was first developed under the name Orange, then later changed to Machina then finally to Elephants Dream since the people working on the movie could not decide how "Machina" would be pronounced. The movie is 11 minutes long.
