A timelapse taken using a HD webcam mounted on a roof overlooking Camden Town. A 1600x1200 pixel image was captured every 5 seconds resulting in over 17000 images and 24 Gb of storage.

While not anywhere near the quality of a DLSR it does provide a quick and easy way to capture long duration timelapses - a tutorial is online at digitalurban.blogspot.com/2008/11/tutorial-torch-webcam-hd-timelapse.html for those interested.

Note the build up and melting of the snow on the lens, captured during the heaviest snow fall in London for 18 years.
