Office Voodoo is an interactive film installation using exclusively live action footage and running on a real-time, shot-based editing engine that fluidly assembles the film as it is being watched, while respecting the conventions of continuity editing. Each character in the film is represented by a physical voodoo doll. As viewers manipulate these dolls, they affect the emotions of the people on screen. They can also call the people in the film using their phones.
