There's a real chance you've seen gigapixel city shots before, but they've rarely had a dynamic element -- you've had to be content with that one sliver of time. Now, there's something a little livelier. Lenstore, Nikon and Canary Wharf have partnered on what they say is the first gigapixel timelapse, 24 Hour London. As the name implies, the project provides 7.3-gigapixel snapshots of the city for every hour of the day -- you can see how the roads come to life in the day, or how Tower Bridge illuminates the night. The trick, unsurprisingly, revolves around some robotics.
