Abstract: Visual display means of a vehicle having a body and force means for producing motion change of the vehicle body comprise a vehicle visual display device on the vehicle body including a container, a first liquid fluid in the container, and a second fluid in the container and essentially immiscible with the first fluid. The vehicle visual display device is responsive to the force means to cause a first fluid-second fluid interface, a first fluid-container interface, and a second fluid-container interface, to change in response to the motion change in the vehicle body. Either the first liquid fluid or the second fluid or both are visible through the container. A plurality of the devices in close proximity, such as side by side, provide the especially interesting and pleasing effects of synchronous change as the motion of the vehicle varies.
