Here’s a time-lapse video of last weekend’s San Francisco Bay Bridge construction closure made using a script that grabbed images from the bridge webcams.

PFC! Great video.
Hey Great stuff! Can you tell us more about the type of script? Was it like a flash script that captured an instance of the video or something? This seems like a pretty innovative way to do time lapses.
Any chance you could post the script and explain how you got it into a movie format?
Here’s the linux tcsh commands I used to aquire the images. It just sucks them from the web
once a minute and then renames the image file to some sequential unique name.
while 1
wget http://images.earthcam.com/ecnetwork/hatchmot2cc.jpg
mv hatchmot2cc.jpg `date +%F_%T.jpg`
sleep 60
end
Once I had all the images I ran the following commands to create simple sequentialy numbred
frames in another directory:
set f = 0
foreach i (`find . -name “2009-*”`)
echo $i $f
cp $i hatchmot2cc/hatchmot2cc.${f}.jpg
@ f=$f + 1
end
I then used a utility we have here at work to create the Quicktime movie.
