Panolapse is a tool for adding motion to time-lapse videos, available for Windows and Mac OSX. This was originally developed for use with the HD timelapse sequences in the Blue Eden project (http://www.youtube.com/blueedenhd).
The concept of Panolapse's motion is similar to 360 panorama viewers, allowing you to pan through a scene as if you were inside it. The movements are real-world accurate, allowing for natural panning and essentially acting as a motorized-head.
Panolapse also has other useful features to zoom, deflicker, interpolate RAW metadata, auto-exposure, create videos, and more.
