I wrote a bit more about the concept on my photo blog
here.
To combine the photos into a video I used Sony Vegas. It is a video editing package. It allows the inclusion of photos in the video (along with panning and zooming effects). I suspect that just about any video editing software would work.
To make it work, I first adjusted the default preference for how long a picture would be shown in the video. I think the default in Vegas was 5 seconds. That would have resulted in a day long video. I changed it to something like 0.03 seconds so that I'd get roughly 30 pictures for every 1 second of video. Because my wife shot the pictures at 1 for every 10 seconds, you are watching 300 seconds of real time activity for every second of video.
