You might remember a while ago I posted a few timelapses. One of a sunset and one of me staining the deck. Jeffrey friedl went a step further and wrote a very nice little perl script that you can use to create panning timelapses. Check it out here. Sean McCormack used it to create a nice panning timelapse of a beach that I embed below for your enjoyment:

This is an awesome tool and I'll be using it on some future timelapses.
