Besides the Tube, I probably feature more timlapse videos of London than anything else. 'Timelapse London' was shot by Ben Grubb and features most of your standard timelpase locations: Waterloo station, Houses of Parliament (with a great shot of the clock on Big Ben rotating), Canary Wharf, Battersea Power Station and St. Paul's among others.
Overall, the quality of cinematography is better than average. My only criticism is that the video doesn't really hold any cohesive narrative. It jumps from the West London to East and then back again. Still this is only a minor niggle and the short film deserves more attention than it's received.
