I like the shapes created by moving shadows (see Morning Shadows) and here is another one. As the early morning sun streams in through the blinds it is creates lines. These are then turned into a dancing shadow play by palm leaves gently waving in the wind.

Of course, a photograph is not the same as a video. So getting an image that is interesting requires taking lots of photos and then picking the ones that best express the feeling of the dancing shadows. I took 150 photos and only kept two.
