CHDK software, which allows many new features, one of which is to run timelapse scripts.
So this was my first go at a timelapse of something interesting. This was filmed? shot?, 1 of those, from my balcony. Unfortunately the script I used didnt allow the camera to go into long exposures as it got dark, so I couldnt use the full set of images I took, but still, this is about 935 shots for this timelapse, taken at 5 second intervals, and pieced together into a 20 fps film. I used Picasa to create the movie.
