Elephants Dream is a computer-generated short film that was produced almost completely using open source software, except for the modular sound studio Reaktor and the cluster that rendered the final production which ran Mac OS X. It premiered on March 24, 2006, after about 8 months of work. Beginning in September 2005, it was developed under the name Orange by a team of seven artists and animators from around the world. It was later renamed Machina and then to Elephants Dream after the way in which Dutch children's stories abruptly end.
