The average day in London has been recreated in a stunning visualisation by a social network site that allows users to 'check-in', and show other users where they are. Foursquare broke down the day into the following activities:
Red, at home; Green, food; Light blue, Arts/Entertainment; Yellow, College/Uni; Dark blue, nightlife; Purple, outdoors activity; Orange, shops/services; Yellow, professional; Green, travel/transport.
From the animation, you can easily pick out the morning commute on trains and buses (coloured green). Then, many Londoners check straight into work (coloured yellow). Then, watch the colours change as the day progresses.
