I know I've done rather a lot of time-lapse movies of snow recently. Here is one more. This time I used the interactive maps at http://www.nohrsc.noaa.gov to generate this view of the last two months of winter snow depths.
I think it's pretty cool (the animation that is - not the snow - although that is cool too of course...!).
