British design students have created a digital display system for train cars to give riders a view of the outside world they’re passing. The ‘Canopy’ concept uses flexible electrophoretic (“e-paper”) display panels that would attach to the roof of a train car. The panels would show an ‘ambient’ animation of passing landmarks and weather information, which would be stored on a computer in the train and updated via Wi-Fi.

The possibilities are endless for this display, as advertisers could pay to make their mark with relevant location-based ads.
