Creative Design for Mobile App Home Screen (One Screen) - open to bidding

"overview": People within one area (i.e. University, Shopping mall, Stadium) post various types of content (news, jokes, complains, appreciation, leave memories, or document an incident within the area) since the area contain at least a thousand people, good number of posts will be there. All people within the area see these posts ( and may like or comment). Also people coming later can come and view the notes that were left in a particular location. “Home Screen”: The home screen need to show text, photos, videos posted by people, in a very NOVEL, creative, elegant yet SIMPLE way. We require a revolutionary creative design concept. The design need to be easy on the eye so people can spend longer time on home screen. I require a NOVEL creative design concept for mobile app idea. The creative designer need to focus on coming up with an appealing novel concept then providing the one home screen design. The concept needs to be around certain theme/story that is reflected in the design if possible (what would you call the home screen or the posts!)
