Oyster Card Touches for a Weekday

This still is from an animation produced for an exhibition Sense and the City, which was at the London Transport Museum during 2011-12. The animation shows Oyster card “touch ins” and “touch outs” as people enter and leave the network of tubes and (some) trains, using the ubiquitous smartcard. Reds show a net influx into the system, while greens show a net flow outwards.
