I have been thinking about buying one of those little cameras that does stop motion video, but decided on the much cheaper alternative of a 99 cent iPhone app. I set my phone up while I was at lunch today and let it record what a pretty typical Michigan day is like as far as the weather goes. This time lapse is over about two hours. I was hoping to record until the sky cleared completely, but my battery died. Overall, I give this app a good grade. It is worth playing around with some more.
