Static Subject, Blurred Background

Alright you photo enthusiasts. Here's something fun to do (well, fun for me to see your results). Take a shot of a kid/ adult on a playground equipment (swing, slide, rotating dish etc)- the condition is that you must pan for the shot. So the child/ adult would look static, but the background etc would be blurred due to the motion. Or you could shoot a child/ adult coming down the slide but pan, so that the person looks static, while the background is blurred. Get creative to show us motion on a playground's equipment. Please note that if the background is not showing motion, your entry will be DQ'd- i.e. you shouldn't simply take a photo of a child on a swing without showing motion.
