The next hype after good timelapses seems to be Hyperlapses. A hyper lapse is a similar concept to a timelapse, with the main difference being that the camera movements are significantly greater, and can span dozens of meters. This would be really expensive (and I mean REALLY) to do with dedicated rails and sliders.
There is one theme that intertwines through the tutorial and it is that you approach a hyperlapse in a similar manner that you would approach a sliding panorama – so the focal length has to be long enough to avoid edge distortion, and using pavement stones as guides.
Morten puts his money where his mouth is and has great timelapses on his vimeo stream, all with cleverly executed camera movements:
