A message board system (10) for a vehicle (14) may include a message board (30) that is configured to be coupled to a vehicle structure (32). The message board (30) has a first layer (70) and a second layer (72). The second layer (72) resides adjacent the first layer (70) and is configured such that a portion of the first layer (70) adheres to the second layer (72) to form an image in response to applied pressure on that portion. The message board system (10) may, as an alternative, include a message board housing (98) also configured to couple a vehicle structure (22). The housing (98) includes multiple cells, each of which having a suspension liquid (108) and magnetic particles (110). The particles (110) are pulled through the suspension liquid (108) in response to an applied magnetic field to form an image.
