Wow. Maybe the commercial spinoff will be a TV you can change channels on without having to move any muscles. See Wired News: Brain Waves Make Robot Move

In a video demonstration in Tokyo, patterns of the changes in the brain taken by an MRI machine, like those used in hospitals, were relayed to a robotic hand.A person in the MRI machine made a fist, spread his fingers and then made a V sign. Several seconds later, the robotic hand made the same movements. Further research would be needed to decode more complex movements.
