Time Lapse Video for Exhibition Assessment

Hi fellow bloggers,
 The time lapse video I posted (and especially the camera I used) has people thinking of interesting things we can do with time lapse video. Three of us are currently looking at using time lapse video to assess the success of exhibition design, especially for hands-on activities. The idea is that this would be a more efficient way to do a tracking and timing study. The educator in the group is wondering if anyone has done this before and if so, what were the results. Do any of you know of previous studies of this sort of thing? The time lapse cameras have only come down in price fairly recently, so I think there won't be any previous projects. But if you know of something, could you drop me a line: tmotz@toledomuseum.org

Thanks,
Tim

An update: Although our management did express interest in the concept, the funding request for the time-lapse cameras was denied with instructions to look into other ways to do the same thing, like with our security cameras.  But I would still be interested if anyone knows of a similar project to use time lapse for exhibition assessment.
