A sign with an image of a white shirt on it was placed at the side of route. When seen from afar, the shirt seems to have a stain on it. As we approach the sign in a car, the stain starts “moving” off the shirt. The effect is achieved because the stain is placed on a sign metres in front of the sign. When close to the sign, the stain is off the shirt.

There were high levels of visualization and recall for this action.
