A scenario in the OLED technology area to which intensive thought has already been devoted is the "swarm". The Audi engineers have transformed a vehicle's rear end into a large, continuous light surface, with innumerable small points of light flickering like a swarm of fish. The movements of the red dots follow the movements of the vehicle. When a right turn is made, they flow to the right; when the car is braked, they flow rapidly forwards; the faster the car goes, the faster they move. The following driver can always see right away what the driver of the car in front is doing.
