Here is a quick little movie that I made today with Final Cut Express and my iSight...

I set up my computer to take a snap shot of the trees outside my window from 8am-8pm every 2 minutes and played all the images back in a few seconds and this is what I came up with...if you watch closely you can see the tree in the foreground start to turn brown from top to bottom and start to loose its leaves too!
