Shot with my point-and-shoot Canon SX130 w/ CHDK hack on University of Arizona campus. There was a storm rolling by so I thought I would give time lapse a go on my little Canon. I was skeptical the time lapse would work well because of the window glare, but it was not too bad. I shot with a 5 second interval for about an hour.
