Can You Figure Out the Secret Technique Used in this Timelapse?

T-RECS Timelapse Showreel 2011 #1 from T-Recs (Timelapse Recordings) on Vimeo.

Ordinarily if there’s movement in a timelapse video, it’s constrained to a small area because a dolly or crane system was used to change the position of the camera small distances between shots. The folks at T-RECS came up with a special way to introduce large distance movements into timelapse shots, but are keeping mum on how they did it. Check out the showreel above and see if you can figure out their secret technique.
