The most dramatically different of these, at first glance at least, is the OLED swarm. This transforms the rear of the car into a large, continuous illuminated surface on which a large number of small points of light fluctuate like a swarm of bees or a shoal of fish. Movements of the red dots take their orientation from movements of the vehicle, so when a right turn is made, for example, they flow to the right, and when the car is braked they flow rapidly forwards. The faster the car is driven, the faster the dots move, helping following drivers to gauge its actions.

The swarm is comprised of ‘Organic Light Emitting Diodes’ (OLEDs), which differ from today’s LEDs in that they are formed from an organic material rather than semiconductor crystals. In its basic form the organic material is a paste that can be applied at a depth of just a few thousandths of a millimetre to a flat surface. When an electrical voltage is applied, the molecules in the paste emit photons and the surface lights up.
