It is hard to believe, but in 1821, America already had its first playgrounds -- but they were no more than sandboxes. Playgrounds have changed tremendously since. The formula of slides and swings is no longer the only choice. Now, playgrounds are being created by design stars who provide new experiences informed by contemporary design sensibilities. Playgrounds have become a design phenomenon. These brilliant spaces of great design ideas, instill discipline, foster creativity, and stimulate independent thinking. They depart from the traditional playground, and propose new ways for kids to interact with each other. These new playgrounds demonstrate breakthrough play space concepts, which give a wholly new dimension to the community. Some even look like art installations. Michele Obama, who created the "Let's Move" campaign to fight childhood obesity, teaches us that children need at least one hour a day of physical activity. Take the kids to the playground. It's healthy, it's smart, and it's all made possible by design.
