software - How do I set up a webcam to take one picture each minute for 24 hours (time-lapse)?

I'm not entirely sure if this is the right place to ask this question, but I don't know of a better place. I need to set up a webcam to take a photo every minute for 24 hours, so that it can be compiled into a video that plays them at something like 20fps. However I don't know of software to do this - is there? I'm running GNU/Linux (ubuntu 10.10).
