Cumulonimbus Clouds, Time-lapse

I just filmed this time-lapse video a couple of hours ago. It was late in the day and I was out pushing my 6 month-old boy through the neighborhood when I realized that there was an incredible number of cumulonimbus clouds booming all over. I went back home and got all my gear out, but I have such a limited range of viewing from my home due to trees, houses and hills that I was lucky to get this shot between the trees. I was filming the clouds in the first scene when it suddenly got much darker and my neighbors alerted me to the nasty looking clouds coming at us from behind. I turned the camera around and started filming. I should have left everything alone there so the film would have been smoother. Oh, well practice makes perfect. The pictures were taken with a Canon PowerShot S3 IS and Granite Bay Time-lapse software. I took one picture every 4 seconds. The movie was made with QuickTime Pro playing the pictures back at 30 fps.
