The Avatar Machine is an interesting art project by Marc Owens. He tries to represent the aesthetics and viewpoint common in 3rd person MMOs. Certainly worth checking out his video of the device in action.
Granted the camera position isn’t optimal since it’s basically blocking the view on his own path but it’s an interesting take on the ongoing interweaving of virtual and physical spaces. I especially love the “warning” attached to the avatar machine:
The system potentially allows for a diminished sense of social responsibility, and could lead the user to demonstrate behaviors normally reserved for the gaming environment.
