This app is just an outstanding simulation of a real-beach environment. It is calming, visually engaging, and soothing. If the designers were looking for ideas, the beach sounds could also have an additional selction pop-up choice category (buttoned) to provide some ambient open source music (in an either/or/or both format) added to make it even better (I do that by playing more than a single app at once). I think it was an excellent idea to give you the capability to select wallpaper or screensaver (built in to the app - so you can manually make the shift).
