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.

Any chance you could post the script and explain how you got it into a movie format?

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.
