BMW introduced a new colour-changing car that morphs like a chameleon into different colours to suit the driver's mood. The German luxury carmaker first unveiled its colour-changing E Ink technology at the Consumer Electronics Show last year, but the colour range was limited to black, white and grey. For this year's show, the engineers at BMW have gone "full colour," showing off their i Vision Dee prototype car that can morph into 32 colours and form striking patterns.
