Can't decide on the colour of your next car? Well, BMW has you covered with their all-electric iX Flow, which changes from black to white at the push of a button. The German automobile firm unveiled the chameleon-like sports activity vehicle today at the Consumer Electronics Show, which is being held in Las Vegas, Nevada. The colour changing ability uses the same'E ink' electrophoretic technology built into the screens of e-Book readers, except applied to a special car body wrap. Electrophoresis works by using an applied electric field to separate molecules -- in this case, black and white pigments -- based on their respective electric charges.
