'Brainwave' cap controls computer

I don't even know what to say about this, I've read the stories about the brain controlling the robotic arm but I guess I didn't really expect to see something like this right now. For the simple fact that it is just a cap that you can put on your head without any special implants or surgery is amazing. I think this has surpassed the feelings I had when I saw the story about Human Pacman. :)
