I just came across this photo set of the same view using a time lapse intervelometer device. I was lead to it from a remixed version over on flickr : by 'narphorium' (he explains how he did it in the comments with Photoshop)
Do check the original and the remix, both are really good pieces of work.
On the original page if you go down to the second picture, you'll see that you get all 6 pictures used in both cases by hovering over the image either from right to left or left to right !
