CastAway is our new app for iOS/Android that allows a user to create a Message in a Bottle and track it as it travels to other users around the world. People can comment on your bottle and you may chat with anyone who receives it.
The icon should be an original work that makes good use of color to stand out, but not garishly so. It should be clean, meaningful, simple, and professional. Ideally it should convey the social aspect of CastAway as well as the message-in-a-bottle concept. If the combination proves to be too complex then the social aspect should be stressed. Because of the international nature of the app, the icon should contain no text elements.
To clarify, the image does not necessarily have to be formatted for IOS (i.e. rounded corners, gloss, etc). I have an environment that will do that for me with a given image. If borders, gloss, etc are important to your design then, by all means, please include them. I'm mainly looking for something clean, attractive, meaningful, and not cartoonish.The final image should be scalable from 1024x1024 down to 57x57 (PNG format).
Also, I don't simply want a typical message-in-a-bottle icon . There are tons of those online that I could purchase and create an icon myself. I'm looking for something a bit more creative.
