Design Iphone/Ipad Icon for a new Photography App

Please design an Icon for a new photography app for the iphone. The icon must contain a very beautiful but still very simple image, where in the centre of the icon motion/dynamic should be shown. I give an example: a city with cars in the middle. Customer should clearly be able to distinguish that the cars are moving and all the rest of the photo is still. This is very hard to do, but creative users like you are definitely able to do that. Have a great day
