care to share the technical aspects of how this was shot ?[/QUOTE]

I just left camcorder for whole that time on auto settings and that's pretty much it. However it went zoom-mental just before it got dark, but in the end I cut off most of boring night shoots. The bigest job was in editing with speeding up and panning. Heavily time consuming, especially because it was done in HD and I wanted to preserve the quality.
I know it probably would be easier to do this with regular camera but I don't have one
