Whisp: If walls could talk, what would they say..?
Whisp allows its users to anonymously leave a short sound bit called a "whisper" hidden in a location. Other users who come near the location can listen to the whispers left by others. Whether it's funny, information, trivial, or completely random, anyone can post whispers anywhere! Users can upvote and downvote whispers, and popular whispers can grow into "shouts."
