I've got a crappy webcam set up in my back yard taking one photo an hour. Each photo gets added on to the end of a video that runs at 24FPS. So each hour the video grows by 1/24 of a second and each day the video grows by 1 second. My plan is to leave it up for a year so you'll get a year of backyard action in just over 6 minutes. Come back tomorrow (or in an hour!) and see the progress.
