I love this image. It reminds me of movement and rhythm. The line right down the middle of the images create symmetry, creating balance in the image, as well as draws the eye across the image. It has a sort of Yin Yang effect. This image is a great example of Principles of Design http://www.youtube.com/watch?v=AmEIWgFYtGU If u click on this image, it is linked to images that a great example of symmetry.
