ABSTRACT:
A display panel includes a casing, a number of parallel display elements rotatably mounted within the casing, a mass that can move within the casing, and a mechanism with which the mass interacts to affect rotation of the display elements. A base attaches the display panel to a motor vehicle dashboard for observation by passengers, such that upon acceleration and deceleration of the motor vehicle, the mass moves to affect periodic display changes.
