The 12-minute video below, "Tears of Steel," was made using Blender, a free open source 3D software package. The effects are top notch, along with the story. I was very impressed and enjoyed it. Filmed in Amsterdam, the Netherlands. Check Blender.org for more info and to download the software and Tears of Steel's website for lots of info about the making of the film, which was crowd-funded. I like the robots, which remind me of robots from Critical Mass Games.
