"Tears of Steel" was realized with crowd-funding by users of the open source 3D creation tool Blender. Target was to improve and test a complete open and free pipeline for visual effects in film - and to make a compelling sci-fi film in Amsterdam, the Netherlands.

The film itself, and all raw material used for making it, have been released under the Creatieve Commons 3.0 Attribution license.
Tears of Steel sponsored by Google, NVIDIA, Hewlett-Packard Workstations and other companies. The film takes 12 minutes to play, and it's suitable for 12 years and older. Well, a good free movie for this weekend, right? :)
