what did you use to take pictures from your webcam periodically? If it's a python script, could you please share your code with us?

Here's a quick script I whipped up. No warranty, etc. Also, you need OpenCV installed.

I snap a picture every time I make a git commit. It's an easy way to ensure that I'm sitting at the computer.

I used isightcapture (The original source is offline, but i think this is the same thing http://distfiles.macports.org/isightcapture/)

https://gist.github.com/4477040 is the cron script I use on a 10 min interval.

There might be other ways to do this now days, but i've used this successfully for a few years.
