When I came back later that day, I found a strange weather phenomenon on the video!
Time lapse surprises
Back in 2007 I was experimenting with a (brilliant btw.) software that takes snapshots on the Macbook with the builtin webcam every couple of minutes and then stitches them together into a movie.
I left it pointing out one of the windows to the ocean front as I wanted to see the patterns by which the ships move in the harbor.
