No pictures but the system works as follows,
The signal required is the Localiser which is fed to the PVDs. It is used primarilly for roll out control of the aircraft. Any deviation from the centre line is fed to the PVD which makes the barbers pole rotate in such a way that it makes you feel like the aircraft is moving off the centre line. When the deviation is corrected the barbers pole once again stops moving.
A good way of experiencing a similar feeling is to sit on the flight deck on an aircraft outside a hangar and the hangar doors are being opened. Concentrate on the flight deck instruments and the movement of the hangar doors in your parapherial vison will make the aircraft seem like its moving.
