London Transport Museum's current exhibition focuses on 'smart, connected and on the move’ London, the city that never stands still. This beautiful animated data visualisation captures the ceaseless flow of movement across London as Oyster card touch-ins and touch-outs at tube and rail stations bloom across a 24-hour period. As the proportion of touches changes from mainly touch-ins to touch-outs, the colours of the circles changes from red to green. The circles grow and shrink as the numbers of touches change and the pattern reverses in the evening.
