When I think of the term Open Source, I, like a lot of people I imagine, think of web based software. But the concept of Open Source (which in short means that anyone is free to use or redistribute something, and the code or instructions used to create it), can be applied to not only software but just about anything as well. The folks at the Blender Foundation, have released their second Open Source Movie, called Big Buck Bunny. Not only is the software which they used to make the movie free and open source, so are the assets used in the movie. Anyone can download the 3D models of the characters, backgrounds etc, to learn from, build on, or use in their own projects.The film itself differs signifigantly from the previous one, Elephant’s Dream, which was definitely targeted towards an adult audience and had a dark steam-punk kind of theme. Big Buck Bunny, as the title might imply, is about a large rabbit who lives in the forest and avenges the death of a butterfly… a little more kid friendly. The animation is fantastic as is the overall production, and proof that open source software and projects can work well.
