In the past decade the Blender Institute made six open movies and several other open projects. Each open film has shared more and more assets, code, work processes and tutorials online than the previous one. But, how does it matter what kind of things do we share online, how much of them, when, and to whom? In this talk I wish to move beyond the self-evident political significance of sharing things online (we all know that sharing is good for a better and more just society), and discuss the complexity, cultural logics, and capital creation from sharing, or online gift giving. I will use the Blender community and sharing open movies as an example around which the talk is framed.
