I wrote a little app to take screenshots and webcam shots at the same time intervals. That is how I got my synced picture in picture time lapse. It isn’t ready for public use yet — its just a hacked up thing right now, but I think my project for next LD will be to make it nice and pretty for everyone to be able to use. At destroysound’s suggestion, I’ll also make it command line accessible.

Ah, cool. But any idea how I can record a timelapse without webcam for the NEXT contest? 😛 I like your idea, and if I ever decide that I want to record webcam as well, I’ll use your app.
