Excellent thread idea! Here is a "timelapse" that I did a couple of years ago....
My original intention was to take some still images of planes flying into land on the runway at Sky Harbor with the Phoenix downtown city center in in the background at sunset. What I wound up doing was as the planes flew overhead, with the camera in continuous mode, I just pushed the remote shutter to catch as much of the landing as possible (as the buffer was filling up) so I could then select the shot I wanted.
While I was processing them, I was just slewing from one image to the next and it made somewhat of a movie. So I turned them into a movie. I processed the entire sequence of images in Lightroom, exported and then used Picasa to create a video file. I was using a K5IIs which shoots RAW at ~7 frames per second - which is the playback speed, with the 60-250 at about 120mm.
I've since found that with RAW images on the K5/K5IIs a sequence of 27 is the most I can capture. However, switching over to JPG expands this number substantially, especially if you go to either *** or ** or * star resolution.
All of this is well suited to a fairly quick and short event - like landing an airplane.
