Hey, I'm going to be taking a road trip in a few weeks, and would like to chronicle it much the way I've seen people do before, by recording the whole thing with a webcam. My question is this: Is there an easy way to record video over long periods of time without taking up your entire hard drive? I've got a good 90GB left on my 2.4GHZ 15" MBP, but really don't want to use all of it for a little side project. I'd appreciate recommendations on free or open source solutions that I can use for this project. Thanks a lot!
